Problems solved by technology

However, because there were few shortwave users before, and downlink diversity channel resources were sufficient, few people currently conduct research on the combination of shortwave downlink diversity technology and channel resource allocation optimization, and often use random and uniform allocation based on experience, so the utilization rate of spectrum resources is low. Meet the growing demand for spectrum resources

Embodiment 1

[0136] A specific embodiment of the present invention is described as follows: the system simulation adopts Matlab software, and the parameter setting does not affect the generality; N users and some stations are randomly distributed in a network scene of 500km * 500km, and the transmission power of each transmitter is are the same; the available probability θ of the channel m,f,n and user communication needs p n known, and the number of user channel diversity is fixed; the learning coefficient β is changed according to the actual utility value, and increases with the number of iterations, so that the result gradually converges from the learning and detection process; the simulation results shown are the average after 300 simulations value.

[0137] Considering the short-wave downlink diversity method, the specific operation is as the above-mentioned specific implementation process, until the selection of the transmitter allocation strategy converges or reaches the set number...

Abstract

The invention discloses a transmitter channel allocation model and method in short wave downlink communication. The model is to combine a probability statistics model with a downlink channel diversitytechnology, construct a corresponding user communication probability model and optimize system communication probability by adjusting a downlink transmitter channel allocation strategy. The method includes the following steps: decomposing a problem of large decision space into two sub-problems which are channel matching and transmitter allocation; to solve the channel matching problem, constructing a multi-to-one matching game model, and calculating stable transmitter-channel matching under maximum system expected communication probability; to solve the transmitter allocation problem, constructing a potential energy game model, and calculating an optimal allocation strategy under the maximum system expected communication probability to obtain the optimal allocation strategy; and finally,calculating the system communication probability. The transmitter channel allocation model and method in short wave downlink communication solve the problem of large decision space in short wave communication and ensure the reliability of short wave user communication.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a transmitter channel allocation model and method in short-wave downlink communication. Background technique [0002] Shortwave communication has the advantages of low maintenance costs, simple equipment, and convenient networking, and has great potential in future development. However, the short-wave channel has disadvantages such as unstable propagation quality, serious interference, and limited frequency resources, which limit the development of short-wave communication. For the short-wave downlink transmission process, in order to improve communication reliability, channel diversity is often used. With the increase of short-wave users and service demands, how to efficiently allocate short-wave channel resources becomes more and more important due to limited short-wave spectrum resources. Aiming at the problem of channel resource allocation, there are many stu...
