description The invention discloses an interference suppression method for a cognitive satellite communication system based on resource allocation. The interference suppression method comprises a satellite, a gateway station and K wave beams covered by the satellite, wherein the available bandwidth of the system is divided into F channels, the bandwidth occupied by each channel is recorded as Bc, the number of user terminals served by the system is M, and the channels are allocated to users in a seven-color multiplexing mode; in the communication process, the satellite transmits information to the users through the allocated channels, and problem modeling is carried out by taking the capacity performance of a cognitive satellite communication system as an optimization target; and the optimal value ofthe system capacity is taken as a global optimization value of the cognitive satellite communication system, an optimal resource allocation result is obtained by adopting a simulated annealing optimization method, and the max
