Description

Background Art

[0002] In certain scenarios, there are a lot of active interference in the entire environment. The interferer interferes with the current communication by making a sharp drop in the signal-to-noise ratio of the current communication band through strong power interference on the target frequency band. When there is interference in the physical frequency band, an effective anti-interference solution is to adjust the current communication frequency band to a frequency band that is not interfered with or has less interference. Because each communication standard works on a specific frequency band, the essence of the above process is to adjust the current interfered communication standard to a non-interfered communication standard.

[0003] The spectrum sensing technology in cognitive radio can be used to sense the status information of each frequency band. In the cognitive radio system, unauthorized devices use spectrum sensing technology to distinguish whether a specific frequency band is a valid signal or randomly fluctuating noise. Cognitive radio technology can also use spectrum sensing technology to detect interference and find available spectrum resources. Because each communication standard works on a fixed frequency band, determining the available spectrum resources is equivalent to determining the available standard. After obtaining the currently available spectrum information, it is necessary to select the most suitable communication standard for switching. In a multi-standard wireless communication network, the terminal can simultaneously establish connections with multiple access networks of different frequency bands and transmit information through multiple different transmission paths of the communication standards. However, due to the performance limitations of the communication standard itself and the difference in the transmission performance of different spectrums due to external interference, the communication standards supported by the terminal will have large differences in performance indicators such as transmission rate, bit error rate, transmission power, and average delay. Therefore, when certain channels are severely interfered with, the terminal needs to comprehensively consider the impact of the system performance parameters, adaptively switch the communication system, and use the channel with the global optimal communication system for communication, so as to reduce the impact of interference and improve the network's reliability, transmission rate and anti-interference performance in a denied environment.

[0004] The decisive decision indicator of the vertical switching algorithm based on received signal strength is the received signal strength (RSS). When the received signal strength of the original standard is lower than that of the new standard, the mobile device will switch to the new network. Since the received signal strength is affected by the outside world, it may be unstable, which will lead to frequent switching between standards. Frequent switching will increase the switching delay, seriously affect the communication quality, and lead to a huge waste of resources. Therefore, scholars have proposed optimization schemes on this basis. One type of optimization scheme is to consider the received signal strength in combination with other parameters and add a delay time. When the received signal strength of the new standard is greater than the received signal strength of the original standard, the standard switching will not be performed temporarily. When the delay time is exceeded, if the received signal strength of the new standard is still greater than the received signal strength of the original standard, the switching between standards will be performed. This optimization method reduces unnecessary switching.

[0005] In the process of vertical switching, considering the complex network environment, it is no longer enough to consider only the received signal strength as an indicator, but multiple standard attributes need to be considered for switching. The attributes that can be used for decision-making include signal-to-noise ratio, transmission rate, bit error rate, channel capacity, switching delay, jitter, etc.

[0006] The traditional switching algorithm is a vertical switching algorithm based on received signal strength, and the decisive decision indicator of the algorithm is the received signal strength. When it is detected that the received signal strength of the currently used standard is lower than the received signal strength of another optional standard, the mobile device will automatically switch to the new network with a stronger received signal. However, the received signal strength is a performance indicator that is easily affected by external factors. Whether it is the obstruction of buildings, changes in weather conditions, or multipath effects, it may cause unstable fluctuations in the received signal strength. This instability makes the switching algorithm based on received signal strength easy to misjudge, which will eventually lead to frequent switching back and forth between standards. Frequent switching will increase the switching delay, seriously affect the communication quality, and lead to a huge waste of resources. Summary of the invention

The advantage of this method is that when the transmitter and the receiver are in a state of relative movement, the communication standard can be adjusted according to the actual situation, which improves the flexibility and stability of communication.

[0026] Furthermore, by setting a judgment threshold to filter out communication modes that are not interfered with, and forming a candidate mode set with modes without noise interference, the system's ability to identify interference can be effectively improved. This step ensures that the system can quickly filter out interfered modes when facing strong interference, thereby reducing the failure rate of signal transmission and improving communication quality.

[0027] Furthermore, the switching decision indicators include transmission rate, signal-to-noise ratio, bit error rate and received signal strength, taking into account multiple communication parameters to ensure that the selected standard not only has a high transmission rate, but also maintains stable communication performance in an interference environment. Through these decision indicators, the system can optimize the channel switching strategy, thereby improving anti-interference capabilities and transmission efficiency.

[0028] Furthermore, the weighted average of the parameters of each communication standard is used for selection to ensure that the switching of each communication standard is based on the global optimal decision. This method weights the characteristics of different communication standards to ensure that the selected standard is superior to other candidate standards in terms of comprehensive performance, thereby improving the overall anti-interference ability of the system.

[0029] Furthermore, the setting of benefit-based parameters and cost-based parameters ensures that when faced with different network conditions, the system can intelligently distinguish which standards have higher benefits and which standards have higher costs, thereby helping the system make better switching decisions and achieving the effect of saving resources and improving communication efficiency.

[0041] Various structural schematic diagrams of the embodiments disclosed in the present invention are shown in the accompanying drawings. These figures are not drawn to scale, and some details are magnified and some details may be omitted for the purpose of clear expression. The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may additionally design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0042] The present invention provides an anti-interference communication method under denial conditions. On the basis of a simple weighted method, a time delay threshold is added to set the time delay threshold, and a trigger condition is added at the same time. The trigger switching condition is the interference noise situation on each standard. When the interference noise appears, the optimal standard is selected through a switching algorithm to perform standard switching. The time delay threshold is set to improve the reliability and stability of the switching and avoid waste of resources. On the basis of a multi-standard communication standard switching algorithm, the simulation implementation of the anti-interference system under the denial environment is completed. By jointly optimizing the signal-to-noise ratio, bit error rate, transmission rate and received signal strength under different communication standards, the multi-standard communication system is switched to work under a communication standard with the best performance in real time, thereby improving the transmission efficiency and safety performance of the multi-standard communication system.

[0043] See also Figure 1The present invention provides an anti-interference communication method under a denied condition, comprising the following steps: S1. Set the transmission power strength of each communication standard and select a suitable communication environment according to the actual application scenario; at the same time, dynamically adjust according to whether the transmitter and the receiver are moving relative to each other. Different communication scenarios will correspond to different wireless transmission losses; Set the transmission power strength of each communication standard on the scene setting page , select the scene and whether the transmitter and receiver are relatively moving. Different scenes will correspond to different wireless transmission losses. Therefore, the setting of step S1 determines the subsequent standard switching index.

[0044] S2. In all communication modes, based on the detection results of interference noise, accurately determine whether there is interference noise; By setting the threshold judgment, the undisturbed standards are screened out, and these noise-free standards are combined into a candidate standard set. ; The severely interfered standards are eliminated, the number of standards entering the candidate standard set is reduced, and the computational complexity of subsequent steps is reduced.

[0045] In the decision-making process of standard switching, the interference noise of each standard is fully considered. When the interference noise of a certain standard exceeds a certain threshold, it is regarded as a condition to trigger switching. It is judged whether there is interference noise in all available links, and the standard that is not interfered is selected to form a set. as follows: (1) in, It is The noise of a network, Indicates the set noise threshold.

[0046] S3. Calculate the set based on the data Switching decision indicators for medium standards; The switching decision indicators are selected as transmission rate, signal-to-noise ratio, bit error rate and received signal strength.

[0047] The bit error rate comes from the real-time detection of the interference identification module.

[0048] The received signal strength is calculated by the difference between the base station's transmitted signal power and the wireless transmission loss.

[0049] The received signal strength reflects the actual receiving strength of the base station's transmitted signal after the wireless transmission loss, and is an important factor in ensuring communication stability. The Okumura-Hata model is used in the present invention to calculate the radio signal propagation path loss. Urban areas take into account the impact of buildings, roads and man-made structures on the signal, as well as the multipath effect and terrain undulation factors, while suburban areas pay more attention to the impact of natural terrain on signal transmission. Hilly terrain can be set with a correction factor based on suburban loss. The terrain parameters of the hills can be expressed by the "terrain undulation" height. It refers to the height difference between 90% of the terrain undulation and 10% of the terrain undulation within a range of 10km from the receiving point to the transmitting point. It can be seen from the inspection data that the correction value increases with the increase of the terrain parameters. It is generally believed that the relative height of the hills does not exceed 200m. In the present invention, it will be taken as 200m, and the corresponding correction value is -16dB. Therefore, when calculating the hilly terrain in this project, the transmission loss of the open suburbs is first calculated, and then the correction factor of the hilly terrain is added.

[0050] The standard formula for median path loss in urban areas is: (4) For large cities: (5) (6) For small and medium-sized cities: (7) The path loss correction for suburban areas is: (8) The path loss correction for hilly terrain is: (9) in, is the operating frequency, is the effective antenna height of the base station transmitter, is the effective antenna height of the mobile station receiver, is the distance between the transmitting and receiving antennas, is the correction factor for the effective antenna height of the mobile station receiver, is the correction factor for hilly areas.

[0051] Therefore, the received signal strength is expressed as: (10) The signal-to-noise ratio is calculated by the ratio between the transmit power and the noise power, as follows: (2) The transmission rate is calculated using Shannon's formula.

[0052] (3) In order to more accurately calculate the wireless transmission loss, the present invention adopts the classic Okumura-Hata model.

[0053] S4, normalizing each parameter to eliminate the dimensional differences between different parameters; The normalized parameter value is , after weighted summation, the weighted average value of the parameters of each communication standard is obtained; step S4 comprehensively considers the influence of multiple key factors on standard switching, thereby improving the rationality and accuracy of the switching decision.

[0054] In order to ensure the fairness and effectiveness of each performance parameter in the decision-making process, the normalization method is used to convert each parameter value into a dimensionless value under a unified scale.

[0055] The performance parameters of wireless networks are divided into benefit parameters and cost parameters. Benefit parameters, such as received signal strength, should be as large as possible, while cost parameters, such as bit error rate, should be as small as possible. The benefit parameters and cost parameters are normalized using equations (8) and (9) respectively, and the parameter values ​​can be normalized to between [0, 1].

[0056] (11) (12) in, Indicates The network's parameter values, The values ​​are 1, 2, 3, 4, The value of is 1, 2, 3, 4. express The maximum value of the parameter, It means The minimum value of the parameter. Indicates the normalized value. For benefit-based parameters, if the actual network parameter is less than The minimum value of the parameter, i.e. ,but is 0; if greater than The maximum value of the parameter, i.e. ,but is 1. For cost parameters, if the actual network parameter is less than The minimum value of the parameter, i.e. ,but is 1; if it is greater than The maximum value of the parameter. ,but is 0.

[0057] The normalized value obtained Perform weighted summation according to the following formula to obtain the weighted average value of the parameters of each communication standard.

[0058] (13) in, represent The candidate communication system The first Normalized attribute values, Represents the weight value assigned to the corresponding attribute.

[0059] S5, perform secondary selection based on the weighted average value, find out the format with the highest weighted average value, and switch; Step S5 ensures the accuracy and efficiency of the mode switching and improves the overall performance of the wireless communication system.

[0060] In order to avoid frequent switching and resource waste caused by the ping-pong effect, the present invention sets a time delay threshold; when the switching clock exceeds the threshold, vertical switching to the system with the highest weighted average value is performed; otherwise, the hysteresis delay is accumulated and the above process is repeated. This design ensures the reliability and stability of the switching decision.

[0061] S6. Display the entire system switching process through dynamic graphics.

[0084] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can usually be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0085] The present invention proposes a multi-standard communication switching strategy based on an improved simple weighted method, and demonstrates its efficient switching capability and anti-interference performance in a complex electromagnetic environment through experimental data: by introducing a time hysteresis threshold, the number of switching times is reduced by 40%, thereby reducing the impact of the ping-pong effect. This shows that the strategy can significantly improve the stability of the system; at 0.05 milliseconds and 0.075 milliseconds, the algorithm successfully identifies interference and performs switching, ensuring that more than 90% of the network transmission rate remains stable, which is 15% higher than the traditional method; in the simulation, the switching success rate reached 98% in scenarios involving shortwave, ultra-shortwave, LTE, satellite communications and other standards, indicating that the algorithm can achieve stable and efficient communication standard switching in a variety of complex environments.

[0086] Experimental data show that the present invention effectively enhances anti-interference capability through multi-communication mode switching, and can maintain a high transmission rate and stability in a high-interference environment. The system comprehensively considers multiple indicators such as signal-to-noise ratio, transmission rate, bit error rate, etc., intelligently selects the optimal communication mode, reduces unnecessary switching, and significantly improves resource utilization efficiency and communication quality.

[0087] See also Figure 2 , which is a multi-standard switching simulation diagram of the present invention.

[0088] The present invention can complete the switching simulation between multiple standards and meet the requirement of switching standards of no less than three types. The standards include shortwave, ultra-shortwave, mobile communication and satellite communication. At the same time, the transmission rate of the selected standard changes with the switching process. Since there is inevitably a certain delay in the process from sensing detection to standard switching, the transmission rate first shows a downward trend when encountering interference, but then as the standard switching is completed, the transmission rate is gradually restored, showing a trend of first decreasing and then increasing.

[0089] See also Figure 3 , which is a demonstration diagram of the switching process of the present invention.

[0090] The present invention presents the entire system switching process in a dynamic graphics manner. Figure 2 This is a picture showing the complete switching process. The interference situation and the changes in various parameter indicators of the currently selected standard are also shown during the switching process. The bit error rate, transmission rate and signal-to-noise ratio change with the change of interference situation.

[0091] In summary, the present invention provides an anti-interference communication method and system under denial conditions, which enhances the anti-interference capability, provides reliable communication services in a strong interference environment, and comprehensively considers multiple indicators such as transmission rate, signal-to-noise ratio, bit error rate, and received signal strength, intelligently selects the optimal communication format, reduces unnecessary switching and resource waste, and thus improves communication efficiency and stability. This method can achieve efficient format switching in a complex environment and optimize resource allocation, and is particularly suitable for military communications and emergency communications, which require highly anti-interference and stable transmission.
