A blind parameters estimation algorithm based on forward difference of power spectral density is presented to solve the problems in co-channel multiple signals processing. The proposed algorithm can fast and accurately estimate such parameters as number of signals, center frequency, signal power, noise power and signal to noise ratio of the mixed signals. Both theoretical analysis and simulation results show that the algorithm is effective.
