Aiming at the low data rate of traditional direct sequence spread spectrum, M-ary spread spectrum and code shift keying underwater acoustic spread spectrum communication, a new combine method of M-ary code shift keying underwater acoustic spread spectrum communication is proposed based on the small Kasami sequence with good self and mutual correlation. Different sequence information and the same sequence code phase information are used in this method. The influences of self and mutual correlation function on M-ary code shift keying underwater acoustic spread spectrum communication over gaussian and fading channel are analyzed. The performances under the two kinds of channels are simulated. The simulation shows that the ability for M-ary code shift spread spectrum to overcome the noise is better than for the direct sequence spread spectrum, M-ary spread spectrum and code shift keying spread spectrum. The comparative experiment is conducted to compare the M-ary spread spectrum, code shift keying spread spectrum and M-ary code shift keying spread spectrum in the pool. The M-ary code shift keying communication rate of 256.3 bps with no transmitting error in 104 bit data volume is realized.
