Four algorithms’ performance comparison under the same SNR. Figure 5 indicates the four algorithms under the same SNR performance simulation curve comparison as follows: when the false alarm probability is 0.1, the detection probabilities of BCS, WBCCSS, MTCS, and paper algorithm were 0.3328, 0.3815, 0.5246, and 0.7925, so the joint spectrum signal detection algorithm compared to BCS, WBCCSS, MTCS algorithm, and spectrum detection has better performance, and from the simulation curve, it can be found using the Dirichlet process that this can be achieved within each group shared with shearing section at parameters. The process fully considers the perception of the temporal correlation of data compression. The performance of the algorithm is obviously better than BCS, WBCCSS, and MTCS
