摘要: The invention discloses a rapid channel estimation and signal synchronization method suitable for an underwater acoustic modem, is the field of real-time online demodulation modem. communication modem physical layer data link block pilot designed, Fourier transform subspace projection are utilized to realize decoding process channel, meanwhile, periodic autocorrelation characteristic pseudorandom sequence decorrelation synchronization. Compared with general time domain method, thealgorithm has advantages that algorithm can be rapidly realized by using systems such as digital processor (DSP), programmable gate array (FPGA) like, operation complexity reduced while ensured. especially sparse estimation.
