a new semi blind signal preprocessing algorithm (second-order cyclostationary BSS algorithm pPSoCBSS-pre-processing) is proposed. The algorithm is used to pre process the signal
so that the source signal has a controlled cycle stable characteristic
and the signal is effectively separated at the receiving end. Love method based on the transmitter source signal preprocessing
channel identification and signal separation
so that the receiver can estimate the channel mixing matrix accurately
and has excellent anti noise characteristics
this method even in underdetermined condition also can be identified and the channel performance is not lost. At the same time
measured through the computer simulation of the separation matrix estimation effect with the PI index
and compared with the JADE algorithm and SOBI algorithm
the simulation results show that the algorithm has better performance than the PI index of two kinds of traditional algorithm.
