Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a method for alternately sampling a signal, a radio transceiver, a storage medium, and an electronic device. Background Art

[0002] In a wireless communication system, signal transmission and reception are the core functions of a radio signal transceiver. On a radio signal transceiver, receiving a wireless signal usually requires sampling the radio signal to achieve reception of the radio signal. Currently, in order to achieve the function of receiving radio signals, a radio signal sampler, such as an ADC (Analog-to-Digital Converter), is usually configured on the radio signal receiver. Therefore, the sampling rate of the signal sampler has become a core factor affecting the radio signal reception performance. In order to improve the signal reception performance of the radio signal transceiver, a signal sampler with a higher sampling rate is required. However, there is an upper limit to the sampling rate of the signal sampler. Relying on a signal sampler with a higher sampling rate cannot effectively improve the signal reception performance of the radio signal transceiver.

[0053] In this embodiment, a method for alternately sampling a signal is provided, which is applied to the above-mentioned computer terminal. Figure 2 The present invention is a flow chart of a method for alternately sampling a signal according to an embodiment of the present application. The signal acquisition system includes a delay controller, a plurality of signal samplers and a processor. The signal output end of the delay controller is connected to the signal input end of each of the signal samplers. The processor is respectively connected to each of the signal samplers and the delay controller. The method is applied to the processor. The process includes the following steps:

[0054] Step S202, selecting a plurality of target samplers for sampling the target signal from the plurality of signal samplers according to the sampling rate requirement for the target signal, wherein the plurality of target samplers are used to alternately sample signal segments corresponding to a plurality of sub-time periods within a unit time period in the target signal;

[0055] Step S204, configuring initial delay information for each target sampler according to the sampler information of the plurality of target samplers, wherein the initial delay information is used to indicate the starting time point of the signal segment sent by the delay controller to the corresponding target sampler in the target signal, and the sampler information is used to indicate the signal sampling performance of the corresponding target signal sampler;

[0056] Step S206, adjusting the initial delay information according to the target delay information to obtain the target delay information corresponding to the target sampler, wherein the target delay information is used to indicate the signal transmission delay between the delay controller and the target sampler;

[0057] Step S208: Control the delay controller to send the target signal to the target sampler according to the signal sending delay indicated by the target delay information.

[0058] Through the above steps, a delay controller and multiple signal samplers are deployed in the signal acquisition system, and then when it is necessary to sample the signal, multiple target signal samplers are screened out from multiple signal samplers according to the sampling rate requirements of the target signal, and then the initial delay information can be configured for each target sampler according to the sampler information that characterizes the sampling performance of the multiple target samplers on the signal, and the initial delay information is adjusted by the target delay information indicating the signal transmission delay between the delay controller and the target sampler, so as to obtain the target delay information of the target sampler, and then the delay controller controls the delay of sending signals to multiple target samplers according to the target delay information to achieve alternating sampling of the target signal, compressing the time required for sampling the target signal, and improving the sampling efficiency and sampling accuracy of the signal. The problem of low sampling efficiency of the signal in the related technology is solved, and the technical effect of improving the sampling efficiency of the signal is achieved.

[0059] Optionally, in the embodiments of the present application, Figure 3 is a hardware connection diagram of a signal acquisition system according to an embodiment of the present application, such as Figure 3 As shown, the signal acquisition system includes a delay controller, multiple signal samplers and a processor, wherein the signal output end of the delay controller is connected to the signal input end of each signal sampler, and the processor is respectively connected to each signal sampler and the delay controller.

[0060] Optionally, in an embodiment of the present application, the delay controller is a device used to perform time delay control on a signal entering a signal sampler. The delay controller may be, but is not limited to, a DDL (Digital Delay Line), an FPGA (Field-Programmable Gate Array), an ASIC (Application-Specific Integrated Circuit), etc. This solution does not limit this.

[0061] Optionally, in an embodiment of the present application, the signal sampler is a device for converting an analog signal into a digital signal. In the present application, the signal sampler may be an ADC (Analog-to-Digital Converter), which is not limited in this solution.

[0062] In the technical solution provided in the above step S202, since the number and performance of signal samplers required for different sampling rate requirements of the target signal may be different, it is necessary to screen out multiple target samplers for sampling the target signal from the multiple signal samplers according to the sampling rate requirements of the target signal. For example, if the sampling rate requirement is 2 Gbps, and the maximum sampling rate of each ADC (signal sampler) in the system is 1 Gbps, the sampling rate requirement can be met by two 1 Gbps ADCs.

[0063] In the technical solution provided in the above step S204, the sampler information is a parameter used to characterize the signal sampling performance of the signal sampler. The sampler information may include but is not limited to the sampling rate, input bandwidth, clock stability, power consumption, etc. of the signal sampler, and this solution does not limit this.

[0064] Optionally, in an embodiment of the present application, the initial delay information is used to indicate the starting time point in the target signal of the signal segment sent by the delay controller to the corresponding target sampler, so that the signal sampler can determine the starting time for sampling the target signal according to the starting time point indicated by the initial delay information.

[0065] Optionally, in an embodiment of the present application, initial delay information may be configured for each target sampler according to the sampler information of the target sampler to ensure that each signal sampler can start sampling the target signal at a specific phase point. A signal sampling amount corresponding to each target sampler may be generated according to the sampling rates of multiple target samplers, that is, more signal sampling amounts may be allocated to signal samplers with higher sampling rates, and then target signal segments to be sampled by the target samplers may be divided for the target signal samplers in multiple sub-signal segments of the target signal according to the signal sampling amounts, and then the start time information of the target signal segment in the target signal may be determined as the initial delay information.

[0066] In the technical solution provided in the above step S206, the target delay information is information that characterizes the effect of environmental factors on the delay of signal transmission between the delay controller and the target sampler. The target delay information may include but is not limited to signal-to-noise ratio, PCB wiring length, ambient temperature, etc., and this solution does not limit this.

[0067] Optionally, in an embodiment of the present application, the signal transmission delay between the delay controller and the target sampler may be affected by various external factors such as noise, PCB wiring length, ambient temperature, etc. If it is not accurately adjusted, it may cause misalignment of the signal sampling points and affect the accuracy of signal acquisition. By using the target delay information to adjust the initial delay information, it can be ensured that even if there are delay differences caused by external environmental factors, the signal acquisition system can maintain accurate synchronization of signal acquisition in each channel.

[0068] In the technical solution provided in the above step S208, accurate control of the delay controller can be achieved to ensure that the signal reaches the target sampler accurately according to the requirements of the target delay information.

[0069] As an optional implementation manner, configuring initial delay information for each target sampler according to the sampler information of the plurality of target samplers includes:

[0070] Acquire a target sampling rate of each target sampler, wherein the target sampling rate is used to indicate the number of signals sampled per unit time by the corresponding target sampler, and the sampler information includes the target sampling rate;

[0071] Allocate a target signal segment in the target signal to be sampled by the target sampler to each target sampler according to the target sampling rate;

[0072] The starting time information of the target signal segment in the target signal is determined as the initial delay information.

[0073] Optionally, in an embodiment of the present application, according to the target sampling rate of the target sampler, the system may divide the input target signal into multiple sub-signal segments, each sub-signal segment may be sampled by a target sampler, and then the start time information of each sub-signal segment may be determined as the initial delay information of the target sampler corresponding to the signal segment.

[0074] As an optional implementation manner, allocating a target signal segment in the target signal to be sampled by the target sampler to each target sampler according to the target sampling rate includes:

[0075] Generate a signal sampling amount corresponding to each of the signal samplers according to the target sampling rates of the plurality of target samplers, wherein the signal sampling amount is used to indicate the amount of signal allocated to the corresponding target sampler for sampling in each sub-signal segment included in the target signal, and the sub-signal segment is a signal transmitted in one unit time in the target signal;

[0076] The target signal segment is planned for the target signal sampler in each of the sub-signal segments included in the target signal according to the signal sampling amount.

[0077] Optionally, in an embodiment of the present application, a signal sampling amount corresponding to the rate ratio may be allocated to each signal sampler according to the relative ratio between the sampling rates of the target samplers, thereby ensuring that each target sampler can collect signals uniformly and efficiently while meeting its sampling rate requirements.

[0078] Optionally, in an embodiment of the present application, target signal segments can be planned for the target signal sampler in each sub-signal segment included in the target signal according to the signal sampling amount, wherein the target signal segments can be arranged continuously or discretely in the sub-signal segments. Figure 4 is a schematic diagram of a target signal segment being arranged continuously in a sub-signal segment according to an embodiment of the present application, such as Figure 4 As shown, the total amount of signals included in the sub-signal segment is 120. Assuming that collector A can collect 50 signals per unit time and collector B can collect 100 signals per unit time, according to the rate ratio of collector A and collector B, collector A is allocated to collect 40 signals and collector B is allocated to collect 80 signals. Moreover, collectors A and B can collect all the allocated signals per unit time. At this time, the target signal segment corresponding to collector A is target signal segment A, and the target signal segment corresponding to collector B is target signal segment B.

[0079] Optionally, in the embodiments of the present application, Figure 5 is a schematic diagram of a discrete arrangement of target signal segments in sub-signal segments according to an embodiment of the present application, such as Figure 5As shown in the figure, assuming that sampler A can collect 30 signals per unit time and sampler B can collect 60 signals per unit time, according to the rate ratio of sampler A and sampler B, sampler A is allocated to collect 40 signals and sampler B is allocated to collect 80 signals. However, if the sampler A collects 30 signals per unit time and sampler B collects 60 signals per unit time, Figure 4 If the allocation is performed in the manner shown, then according to the sampling rate of sampler A, it can be known that it is unable to collect the first 40 signals within a unit time. At this time, sampler A can be made to collect target signal segment A1 and target signal segment A2 at the same time, and sampler B can collect target signal segment B1 and target signal segment B2 at the same time. This allocation method can enable sampler A and sampler B to collect their allocated signal amounts within a unit time. At this time, the target signal segment corresponding to collector A is target signal segment A1+A2, and the target signal segment corresponding to collector B is target signal segment B1+B2.

[0080] As an optional implementation manner, generating a signal sampling amount corresponding to each signal sampler according to the target sampling rate of the plurality of target samplers includes:

[0081] Calculating a sampling rate ratio of a plurality of the target samplers according to the target sampling rate;

[0082] According to the sampling rate ratio, a corresponding signal sampling amount is allocated to each target sampler from the signal amount included in the sub-signal segment.

[0083] Optionally, in an embodiment of the present application, the system can reasonably allocate the signal sampling amount of each target sampler according to the sampling rate ratio of the target sampler. For example, there are three target samplers in the signal acquisition system, and the sampling rates are 2Gbps, 4Gbps and 6Gbps respectively. The sampling rate ratio of samplers A, B and C is 1:2:3. Then, according to the sampling rate ratio (1:2:3) calculated above, the corresponding signal sampling amount is allocated to each sampler from the total signal amount included in the sub-signal segment. Assuming that the period of the target signal is 1 microsecond, and the bandwidth and characteristics of the signal allow the total number of samples collected within 1 microsecond to be 12,000, the total signal amount included in the sub-signal segment is 12,000. Then, within 1 microsecond, the signal sampling amount of sampler A is 2,000 samples; the signal sampling amount of sampler B is 4,000 samples; and the signal sampling amount of sampler C is 6,000 samples. By calculating the sampling rate ratio and reasonably allocating the signal sampling amount, it is possible to ensure that the relative proportion of signal acquisition between samplers matches their sampling rates, thereby improving the efficiency of alternate sampling of signals.

[0084] As an optional implementation manner, before adjusting the initial delay information according to the target delay information to obtain the target delay information corresponding to the target sampler, the method includes:

[0085] Acquiring signal acquisition information of the signal acquisition system, wherein the signal acquisition information is used to indicate the signal acquisition quality of signals acquired by using a plurality of the target samplers;

[0086] The target delay information corresponding to each target sampler is generated according to the signal acquisition information.

[0087] Optionally, in an embodiment of the present application, obtaining the signal acquisition information of the signal acquisition system may be by analyzing the single-tone signal output by the signal acquisition system, or may be by querying the historical signal transmission data of the signal acquisition system and obtaining the signal acquisition information of the signal acquisition system from the historical signal transmission data.

[0088] As an optional implementation manner, generating the target delay information corresponding to each target sampler according to the signal acquisition information includes:

[0089] Determine a target delay adjustment amount corresponding to a target signal-to-noise ratio of a signal sampled by the target sampler from the signal-to-noise ratio and the delay adjustment amount having a corresponding relationship, wherein the signal acquisition information includes the target signal-to-noise ratio;

[0090] The target delay adjustment amount is used to adjust the initial delay information of the target signal sampler to obtain candidate delay information, wherein when the initial delay information is used to transmit a signal to the target signal sampler, the signal sampled by the target signal sampler has the target signal-to-noise ratio;

[0091] In a case where the candidate delay information satisfies a target delay information condition, the candidate delay information is determined as the target delay information of the target sampler.

[0092] Optionally, in an embodiment of the present application, a mapping table including signal-to-noise ratios and delay adjustment amounts may be constructed, and then a target signal-to-noise ratio of a signal sampled by a target sampler may be used as an index to query a corresponding target delay adjustment amount.

[0093] Optionally, in an embodiment of the present application, the target delay information condition may be an indication of whether the sampling quality after sending a signal to the sampler using the adjusted candidate delay information meets the quality requirements. In this embodiment, it may be possible but not limited to determining whether the target delay information condition is met by detecting whether the signal-to-noise ratio obtained by sampling the signal using the candidate delay information is less than a target signal-to-noise ratio threshold. When the signal-to-noise ratio is less than or equal to the target signal-to-noise ratio threshold, it is determined that the target delay information condition is met. Alternatively, it may be possible to determine whether the target delay information condition is met by detecting the number of adjustments to the initial delay information. When the number of adjustments to the initial delay information is greater than or equal to the target number of times, it is determined that the target delay information condition is met.

[0094] As an optional implementation manner, the step of selecting a plurality of target samplers for sampling the target signal from the plurality of signal samplers according to the sampling rate requirement for the target signal comprises:

[0095] Obtaining a sampling rate of each of the signal samplers;

[0096] A plurality of target samplers are selected from the plurality of signal samplers according to a matching relationship between the sampling rate and the sampling rate requirement.

[0097] Optionally, in an embodiment of the present application, multiple target samplers can be screened out from multiple signal samplers through permutations and combinations based on the matching relationship between the sampling rate of the signal sampler and the sampling rate requirement. For example, if the sampling rate requirement of the target signal is 10Gbps, the system can choose to use two 5Gbps samplers in combination, or can choose to use one 2Gbps and two 4Gbps samplers in combination. This screening method can ensure that the signal acquisition system can flexibly respond to various sampling rate requirements based on the sampling rate of the signal sampler and the number of samplers.

[0098] In order to better understand the above process, the above process is described below in conjunction with an optional embodiment, but it is not intended to limit the technical solution of the embodiment of the present application.

[0099] Optionally, the present application provides a hardware implementation method of a time-interleaved ADC. In order to improve the accuracy of automatic fiber delay compensation in a repeater station, multiple ADCs are used to alternately sample the signal to increase the sampling rate of the entire system.

[0100] This solution ensures the consistency of the clock and controls the time point when the signal is input to the ADC, which greatly reduces the requirements for the clock. Figure 6 A hardware implementation method of a time-interleaved ADC according to an embodiment of the present application is shown in FIG. Figure 1 , Figure 7 A hardware implementation method of a time-interleaved ADC according to an embodiment of the present application is shown in FIG. Figure 2 ,like Figure 6 , 7As shown, the ADC uses the same clock, and the phase of the clock entering the ADC is the same, ensuring that multiple ADCs sample at the same time. The sampling points of each ADC are staggered by increasing the delay at the front end. The front-end delay changes the signal time point entering the ADC through PCB wiring and the delay controller. The delay time calculation formula is: t = 1 / (N*fs), (fs is the sampling rate of the ADC, and N is the number of ADCs). Taking a dual-channel 1Gbps sampling rate ADC as an example, the required delay is t = 1 / (2*10^9) = 0.5ns. Through PCB wiring, the delay is controlled to be around 0.5ns, and then the delay control module is controlled through the delay calibration compensation module to compensate the delay to a reasonable range.
