Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a UWB pulse shaping device, method, and storage medium. Background Technology

[0002] Ultra-wideband (UWB) technology is a novel wireless communication technology that achieves GHz-level bandwidth by directly modulating impulse pulses with steep rise and fall times. Pulse UWB (IR-UWB) is primarily used for high-precision positioning (centimeter-level) and sensing applications, specifically for precise tracking of people and moving objects, and making decisions based on real-time scenarios. It provides higher-precision positioning and sensing technologies for transportation, logistics and warehousing, traditional manufacturing, the power industry, healthcare, high-risk chemical industries, tunnels and utility tunnels, construction sites, intelligent robots, and drones, and also serves the Internet of Things (IoT) and other fields.

[0003] IR-UWB signal transmitters typically employ fixed pulse shaping techniques to optimize and shape the pulses to be transmitted. However, the shaped pulses obtained by the IR-UWB transmitter are generally fixed or have limited adjustment range. Furthermore, global transmission spectrum regulations across the 3G to 10G frequency bands have varying transmission power requirements from different countries, each corresponding to a different maximum power spectral density. The use of fixed pulse shaping techniques in IR-UWB transmitters makes it difficult to ensure that the shaped pulses comply with global transmission spectrum regulations while simultaneously allowing the IR-UWB transmitter to operate close to its maximum power spectral density.

[0004] In order to ensure that the shaped pulses in the IR-UWB signal transmitter meet the requirements, the internal structure of the IR-UWB signal transmitter needs to be adjusted in different application scenarios, which is a relatively complicated process. Summary of the Invention

[0017] Furthermore, the pulse detection module is specifically used to determine whether the target pulse signal meets the preset transmission conditions by testing or simulating the target pulse signal.

[0018] Furthermore, the pulse width of the first basic square wave signal is a fixed value, and the delay duration of each delay unit is the same.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0045] Existing pulse shaping devices generally employ fixed pulse shaping techniques. However, different application scenarios have different requirements for the shaped pulses. For example, a fixed pulse shaping technique may generate pulses that meet the requirements of the current application scenario (current transmission frequency and power); however, the same fixed pulse shaping technique may generate pulses that do not meet the requirements of another application scenario (another transmission frequency and power). To make the pulses meet different requirements, it is generally necessary to modify the internal structure of the pulse shaping device accordingly. This modification includes adding or deleting relevant circuit components, the specifics of which are not limited here. In practical applications, multiple modifications to the internal structure may be required based on the needs, which is a cumbersome and difficult process to implement. Therefore, this application proposes a UWB pulse shaping device that can adjust the shaped pulses through flexible shaping configuration to meet the pulse transmission requirements, as detailed below:

[0046] like Figure 1 and Figure 2 As shown, the UWB pulse shaping device provided in this embodiment mainly includes: a basic square wave input module 101, a delay module 102, a shaping configuration module 103, and a power amplifier 104. It is understood that this UWB pulse shaping device can be an IR-UWB signal transmitting device or an optical pulse shaping device; the specific method is not limited here. Preferably, the UWB pulse shaping device is an IR-UWB signal transmitting device. The basic square wave input module 101 transmits the basic square wave signal to the delay module 102. The basic square wave signal, delayed by the delay module 102, is input to the shaping configuration module 103. After configuration, the shaping configuration module 103 transmits the basic square wave signal to the power amplifier 104, where they are then superimposed to form a pulse. It is understood that this power amplifier is generally a digital power amplifier. The delay module 102 includes at least one cascaded delay unit, which is mainly used to delay the signal for a certain period of time. The shaping configuration module 103 includes at least two shaping configuration units, and each delay unit corresponds to at least one shaping configuration unit.

[0047] The basic square wave input module 101 is communicatively connected to the first-stage delay unit in at least one delay unit. This communication connection can be wired or wireless, and is not specifically limited here. The basic square wave input module 101 is used to acquire the first basic square wave signal to be transmitted and input the first basic square wave signal into at least one delay unit to obtain the basic square wave signal before and after the delay corresponding to each delay unit. It can be understood that the first basic square wave signal will generate a corresponding delay after passing through each delay unit to obtain the basic square wave signal before and after the delay. The delay units are generally cascaded, and the delay duration of the first basic square wave signal is the sum of the delay durations corresponding to the delay units it passes through. Each shaping configuration unit is communicatively connected to both ends of the corresponding delay unit before and after the delay. Specifically, the delay unit corresponding to the shaping configuration unit has one end before the delay and one end after the delay by the delay unit. The shaping configuration unit is connected to these two ends respectively, mainly for acquiring the signals at these two ends. The shaping configuration unit is mainly used to determine the second basic square wave signal from the pre-delay and post-delay basic square wave signals of the corresponding delay unit based on the configuration results of the shaping configuration unit. It can be understood that the shaping configuration unit can select the passable signal based on the configuration results, and select the passable signal from the pre-delay and post-delay basic square wave signals of the corresponding delay unit, determining it as the second basic square wave signal. The power amplifier 104, communicatively connected to each shaping configuration unit, is used to receive the second basic square wave signal sent by each shaping configuration unit and superimpose multiple second basic square wave signals to generate the target pulse signal.

[0048] In this embodiment, each shaping configuration unit is communicatively connected to both ends of the corresponding delay unit before and after the delay. Based on the configuration result of the shaping configuration unit, it determines a second basic square wave signal from the basic square wave signal before and after the delay of the corresponding delay unit. Then, multiple second basic square wave signals are superimposed by a power amplifier to generate a target pulse signal. By employing multiple flexibly configurable shaping configuration units, the generated target pulse signal can meet the requirements without changing the internal structure of the UWB pulse shaping device. Furthermore, the UWB pulse shaping device can flexibly optimize itself by adjusting the configuration result of the shaping configuration unit, adjusting the obtained pulse shape to meet various requirements.

[0049] Furthermore, the shaping configuration unit is also used to determine the configuration result of the shaping configuration unit from its optional configurations, and the configuration result of the shaping configuration unit can be flexibly modified. Specifically, the optional configurations of the shaping configuration unit can be: a first identification information corresponding to the pre-delay basic square wave signal of the delay unit, and a second identification information corresponding to the post-delay basic square wave signal of the delay unit; the first identification information and the second identification information can be "1" or "0", which is not limited here, and the content referred to by the first identification information and the second identification information are different. Specifically, the shaping configuration unit is used to: if the configuration result of the shaping configuration unit is the first identification information, then disconnect the communication connection with the post-delay end of the corresponding delay unit and determine that the second basic square wave signal is the pre-delay basic square wave signal; if the configuration result of the shaping configuration unit is the second identification information, then disconnect the communication connection with the pre-delay end of the corresponding delay unit and determine that the second basic square wave signal is the post-delay basic square wave signal. In one implementable scheme, such as Figure 2 As shown, this scheme contains 8 delay units and 16 shaping configuration units. Each delay unit corresponds to two shaping configuration units. In the shaping configuration unit, '1' represents selecting the base square wave signal before the corresponding delay unit's delay, and '0' represents selecting the base square wave signal after the corresponding delay unit's delay. Through these shaping configuration units, the 16 base square waves with different delays are superimposed together by a digital power amplifier to form a pulse. It can be understood that each shaping configuration unit can select either '1' or '0' as the configuration result.

[0050] Furthermore, the UWB pulse shaping device proposed in this application embodiment also includes a pulse detection module. It is understood that the UWB pulse shaping device may include a UWB pulse transmitting device and a pulse detection module, and the pulse detection module is independent of the UWB pulse transmitting device (i.e., the UWB pulse transmitting device does not include a pulse detection module). This pulse detection module is communicatively connected to each shaping configuration unit and the power amplifier, and is mainly used to receive the target pulse signal sent by the power amplifier after the power amplifier generates the target pulse signal, and to detect whether the target pulse signal meets preset transmission conditions. It is understood that the preset transmission conditions mainly refer to meeting global transmission spectrum regulations while allowing the transmitting device of the target pulse signal to operate at near-maximum power spectral density. If the target pulse signal meets the preset transmission conditions, the transmitting device transmits the target pulse signal; if the target pulse signal does not meet the preset transmission conditions, the pulse detection module sends an adjustment configuration command to the shaping configuration unit. This adjustment configuration command is mainly used to adjust the configuration results of the shaping configuration unit. After receiving the adjustment configuration command, the shaping configuration unit adjusts its configuration results according to the command to ensure that the target pulse signal meets the preset transmission conditions. It is understood that the shaping configuration unit can adjust its configuration results only after receiving the adjustment configuration command, or it can adjust the configuration results manually; this is not limited here. The adjustment configuration results modify the configuration results of some or all of the shaping configuration units in the shaping configuration module; this is also not limited here.

[0051] Furthermore, when detecting whether a target pulse signal meets the preset transmission conditions, the pulse detection module can test or simulate the target pulse signal to determine whether the preset transmission conditions are met. Generally, testing or simulation is very fast, allowing testing of all possible configuration results and the resulting target pulse signals, thereby more accurately determining the target pulse signal that meets the preset transmission conditions.

[0052] Furthermore, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, embodiments of this application also provide pulse signals obtained under different shaping configurations, specifically: as follows Figure 4As shown, different countries around the world have different transmit power requirements in the 3G to 10G frequency bands. Specifically, according to the transmit spectrum density regulations of China and ETSI, the power spectral density of the sidelobes needs to be below 70 dBm / MHz to meet the requirements of these regulations. In one feasible scheme, the effects of different shaping configurations can be observed by fixing the base square wave and delay units. The pulse width of the first base square wave signal is fixed, while the delay duration of each delay unit is the same. The following explanation uses a base square wave width of 2 nanoseconds, a delay unit corresponding to a delay duration of 250 picoseconds, and selects HRP (High-Rate Pulse) UWB channel 5, with a center frequency of 6489.6MHz.

[0053] like Figure 2 The 16 shaping configuration units are configured as (11,11,11,11,11,11,11,11), resulting in the pulse signal shown in Figure 5. It can be seen that the difference between the main peak and sidelobes is less than 28.7 dB (-41.3 + 70). Under this configuration, to comply with the relevant transmit spectrum density regulations of China and ETSI, the transmitter cannot operate at maximum power spectral density. That is, to ensure the sidelobe power spectral density is below 70 dBm / MHz, the main peak power spectral density must be below -41.3 dBm / MHz, reduced to -44 dBm / MHz. At this point, the effective transmission distance of the UWB transmitter will be reduced, coverage will be limited, and market competitiveness will decrease.

[0054] like Figure 2 The configuration result of the 16 integer configuration units is (11, 10, 10, 10, 11, 11, 11, 11), which can be obtained as follows: Figure 6 The pulse signal shown indicates a high spectral density. The difference between the main peak and sidelobes is as high as 31 dB, and the sidelobe power spectral density is below 70 dBm / MHz. At this point, the transmitter can operate at maximum power spectral density and complies with the relevant transmission spectral density regulations of China and ETSI.

[0055] like Figure 2 The configuration result of the 16 integer configuration units is (11, 00, 00, 10, 10, 11, 11, 11), which can be obtained as follows: Figure 7 The pulse signal shown shows that the difference between the main peak and the side lobes is close to 34 dB, and the side lobe power spectral density is below 70 dBm / MHz. At this point, the transmitter can operate at maximum power spectral density and complies with the relevant transmission spectral density regulations of China and ETSI.

[0056] This application also provides a UWB pulse shaping method, applied to a UWB pulse shaping device, such as... Figure 3As shown, the specific steps are as follows:

[0057] 301. The first basic square wave signal is subjected to multiple cascaded delay processing to obtain multiple sets of corresponding basic square wave signals before and after delay.

[0058] The pulse shaping device can acquire the first basic square wave signal to be transmitted, and then perform multiple cascaded delay processing on the first basic square wave signal to obtain multiple sets of corresponding pre-delay and post-delay basic square wave signals. It can be understood that after the first basic square wave signal undergoes cascaded delay processing, each delay processing can produce a corresponding set of pre-delay and post-delay basic square wave signals, and the total delay time of the current delay processing is the sum of the delay times of all delay processing performed on the first basic square wave signal.

[0059] 302. From multiple sets of corresponding pre-delayed and post-delayed basic square wave signals, determine multiple second basic square wave signals;

[0060] The pulse shaping device can determine multiple second basic square wave signals from multiple sets of corresponding pre-delay and post-delay basic square wave signals. Specifically, in each set of corresponding pre-delay and post-delay basic square wave signals, at least one corresponding configuration result is determined; it can be understood that each set of pre-delay and post-delay basic square wave signals corresponds to at least one configuration result. Based on the multiple configuration results, multiple second basic square wave signals are determined from the corresponding pre-delay and post-delay basic square wave signals; wherein each configuration result corresponds to one second basic square wave signal.

[0061] 303. Superimpose multiple second basic square wave signals to generate the target pulse signal.

[0062] The pulse shaping device superimposes multiple second-basic square wave signals to generate a target pulse signal. It is understandable that each configuration result can be adjusted according to specific circumstances, and different configuration results will correspond to different target pulse signals. By flexibly adjusting the configuration results, multiple different target pulse signals can be obtained.

[0063] This application also provides a UWB pulse shaping device, such as... Figure 8 The above includes:

[0064] The execution unit 801 is used to acquire the first basic square wave signal to be transmitted, and to obtain multiple sets of corresponding basic square wave signals before and after delay by performing multiple cascaded delay processing on the first basic square wave signal.
