Recognition performance under different channel conditions. In (a), fusion-four is the variation curve of the cooperative recognition results of four receivers with different channel transmission status with SNR. Fusion-two represents the variation of the cooperative recognition results of receivers 1 and 2 with poor channel conditions.
