Description

Technical Field

[0001] The present invention relates to the technical field of communication decision making, and in particular to a decision making method and system based on a communication system. Background Art

[0002] Due to its unique openness, wireless communication systems are extremely susceptible to various intentional and unintentional interferences. Therefore, in existing communication systems, the communication capabilities of communication systems are tested by making interference decisions. In the single communication decision model of the existing wireless system, the intelligent multi-domain anti-interference decision has too large a decision space caused by multiple domains, and the optimal communication parameters cannot be obtained within a limited time. There are problems such as slow convergence speed and poor robustness. In the multiple communication decision model, the interference environment of each time slot will also change, and the duration of each time slot is very short. The communication interference decision and performance evaluation method based on this relies on expert experience and prior knowledge, and has problems such as long interference confrontation interaction time and low interference efficiency. To a certain extent, it is difficult to apply to different wireless communication environments with high real-time requirements. Therefore, it is very necessary to design a decision method and system based on the communication system to improve the interference test effect of communication decision and optimize interference decision. Summary of the invention

[0003] The object of the present invention is to provide a decision-making method and system based on a communication system to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a decision-making method based on a communication system, comprising the following steps:

[0005] Step 1: Construct an interference decision scheme for a single communication in a wireless communication system;

[0006] Step 2: Construct an interference decision scheme for multiple communications in a wireless communication system;

[0007] Step 3: Based on single communication interference decision and multiple communication interference decision, test the current anti-interference effect of the communication system;

[0008] Step 4: Feedback the efficiency of the single communication and multiple communication interference decision-making schemes set in the communication system based on the interference effect of the test.

[0009] According to the above technical solution, the specific steps of constructing an interference decision scheme for a single communication in a wireless communication system include:

[0010] Step 11: In the single communication interference model, the interference control machine transmits an interference signal to interfere with the signal received by the communication receiver, so that the information obtained after decoding is erroneous and normal communication cannot continue;

[0011] Step 12: Construct an interference action selection strategy for the interference control machine when facing the unknown communication state of the interfered party. In the interference action selection strategy, the interference knowledge base is modeled, and the interference action is recommended based on the interference knowledge base. The algorithm is used to obtain effective interference actions in a shorter iteration cycle.

[0012] Step 13: By interacting with the communication environment, continuously obtain feedback from the communication environment, take maximizing the cumulative feedback value as the optimization goal, and estimate the feedback expectation that can be obtained by taking each action;

[0013] Step 14: Select the action that can obtain the maximum expected feedback value. In the scenario of single communication interference, the feedback value is the bit error rate after the interfered receiver demodulates the signal. The jammer can estimate the bit error rate by observing the exchange between the communication transmitter and the receiver.

[0014] According to the above technical solution, the interference decision of multiple communications in the communication system includes:

[0015] Multiple jammers are used to collaboratively make interference decisions. By designating one of the jammers as the control center for interference decision-making, the control center is used to obtain signal information in multiple communication environments in the communication system from the distributed controlled jammers. Various optimized genetic algorithms and ant colony algorithms are used to achieve the optimal configuration of interference resources. Multi-agent reinforcement learning algorithms are used for collaborative interference decision-making of multiple jammers. By interacting with multiple communication environments, an interference strategy scheme for multiple communications in a wireless communication system is constructed.

[0016] According to the above technical solution, the specific method steps for constructing the interference decision scheme for multiple communications include:

[0017] Step 21: During the initialization phase of interference decision making for multiple communications in the wireless communication system, the interference control center randomly groups the nodes in the communication network in each interference cycle, and then selects each group of nodes for interference in turn;

[0018] Step 22: When facing multiple communications with unknown topology, the jammer system interacts with the communication network continuously, and then the jammer center randomly selects nodes for jamming, and continuously increases the jamming history data;

[0019] Step 23: Collect interference actions in multiple communication environments, record feedback information of communication topology networking, establish and update the interference history database, and converge it to a better interference decision;

[0020] Step 24: Based on the interference history data, the importance knowledge of the communication networking nodes is mined, and the knowledge previously recorded by the interference knowledge terminal is updated, and the importance knowledge of the communication networking nodes hidden in the interference history data is also mined simultaneously;

[0021] Step 25: Finally, a knowledge strategy for collaborative decision-making of multiple jammers is constructed based on the mined knowledge graph. According to the constructed strategy, the interference control center is guided to iteratively select the optimal communication networking node combination for further interference, thereby optimizing the interference decision-making scheme for multiple communications in the wireless communication system.

[0022] According to the above technical solution, the method steps for testing the current anti-interference effect of the communication system include:

[0023] Step 31: Use a communication node with a sensing function in the communication system to sense the interference environment, determine whether the current interference environment is a single communication environment or a multiple communication environment, and obtain decision information on the interference type and interference power in the corresponding communication environment;

[0024] Step 32: using a decision node with decision-making function in the communication system to make a decision on the interference suppression method through sensing information, and in the decision scheme, selecting different interference decision methods according to different interference types;

[0025] Step 33: When the communication system is working, the system monitors the interference in the communication channel in real time. After detecting the interference signal, the system identifies the interference signal and estimates the center frequency and bandwidth of the interference signal using a related algorithm. Then, the frequency points with interference are removed from the frequency hopping pattern of the communication system.

[0026] Step 34: During a single communication of the wireless communication system, the interference recognition technology is used to detect and identify the current interference type and parameters, and a corresponding interference decision is made according to the established criteria to adjust the communication frequency, power and coding parameters;

[0027] Step 35: When there is frequency domain interference such as multi-tone and partial band interference in the working frequency band, a frequency domain interference suppression test is performed; when there is interference such as linear frequency modulation and noise frequency modulation in the working frequency band, an interference reconstruction and cancellation test is performed; when there is time domain interference such as pulse interference in the working frequency band, a time domain interference suppression test is performed;

[0028] Step 36: Based on the expert knowledge base in the communication system, the communication benefit matrix is ​​calculated in real time. Based on the benefit matrix of the interfering party and the communicating party in single communication and multiple communications when the strategies of the interfering party are unknown, the benefit of each interference strategy is obtained by solving the benefit matrix, and the benefit is used as the interference effect evaluation result.

[0029] According to the above technical solution, the step of providing feedback on the efficiency of the single communication and multiple communication interference decision schemes set in the communication system includes:

[0030] The interference control center interacts with the single communication and multiple communication environments in the communication system through trial and error, and judges the interference effect of the current strategy from the feedback information obtained, and then determines the next interference strategy based on relevant algorithms or rules;

[0031] The interference control center intercepts the transmission signal of the communication party for feature analysis, extracts multiple features of the transmission signal for online evaluation of the interference effectiveness, and uses the effectiveness evaluation results as rewards for learning. The interference control center selects an interference strategy composed of multi-dimensional parameters, and based on several interference data, forms an interference signal to interfere with the communication parties in the communication system, evaluates the degree to which the communication parties in the communication system are affected by the interference, and uses the maximum and minimum strategies to calculate the minimum benefits of the interference strategies adopted by the single communication party and the multiple communication party in the communication system, and obtains the anti-interference effect produced by the communication system.

[0032] According to the above technical solution, the decision-making system includes:

[0033] An interference decision scheme module, used to construct an interference decision scheme for a communication terminal in a wireless communication system;

[0034] The anti-interference effect test module is used to test the current anti-interference effect of the communication system based on the communication interference decision;

[0035] The decision-making scheme efficiency feedback module is used to feedback the efficiency of the single communication and multiple communication interference decision-making schemes set in the communication system according to the tested interference effect.

[0036] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0037] 1. Construct an interference action selection strategy for the interference control machine when facing the unknown communication state of the interfered party. In the interference action selection strategy, the interference knowledge base is modeled and the interference action recommendation is realized based on the interference knowledge base. The algorithm is used to obtain effective interference actions in a shorter iteration cycle, which can improve the communication decision interference test effect and optimize the interference decision based on the initialization stage;

[0038] 2. By using the interference control center to interact with the single communication and multiple communication environments in the communication system through trial and error, and judging the interference effect of the current strategy from the feedback information obtained, and then deciding the next interference strategy based on relevant algorithms or rules, since the strategy learning process is carried out during the environmental interaction process, the interference strategy finally learned is consistent with the external environment, that is, it can truly achieve effective and reliable interference.
