@@@@Based on analysis of the communication system based on multi-channel cognitive radio, a channel model with parameters is designed, and this model, with GAEA algorithm (Genetic Annealing Evolutionary Algorithm), optimizes the parameters of each channel and rationally allocates the spectrum resources, thus to acquire the maximum transmission efficiency. Performance analysis and simulation on the model indicate the versatility and effectiveness of the algorithm. Meanwhile the relationship between objective function and parameter settings of the channel is discussed, so as to obtain the balance of overall performance.
