最后结合估计的混合矩阵，采用子空间投影算法，对跳频网台信号时频矩阵进行

Finally, the estimated mixing matrix, subspace projection method, the frequency hopping matrix network station underdetermined blind signal separation, according to the estimated DOA, after adjusting the separation sequence subsegment, eventually hopping network signal sorting station.

Finally, combined with the estimated mixing matrix, the sub-space projection algorithm is used to make the frequency matrix of the frequency-hopping network platform under-determined and blind separation, adjust the sequence of the sub-segments after separation according to the estimated DOA, and finally realize the separation of the frequency network signal.

Finally, combined with the estimated mixed matrix, the subspace projection algorithm is used to underdetermine the time-frequency matrix of FH network signals. According to the estimated DOA, the sequence of the separated sub segments is adjusted, and finally the FH network signals are sorted.<br>
