In order to work out a correct solution to the problem which to detecte the FSK signal when the SNR is low,we use bispectrum based on the parameter model,which can choke the noise and gain the characters.We use the two channels with bispectrum and energy spectral anaysis method for signal detection.The simulation results show that this method works out a correct solution to the problem on the low SNR.The time of signal detection for 128 ways is below 0.4 seconds,and the precision is 0.1 Hz.This technology has been used in some correlative equipment.
