Study on chaotic sequence and RS sequence for underwater communication
Underwater acoustic communication channels are generally characterized as seriously time-space-frequency variant channels with strong multi-path interference, limited bandwidth, severe environment noise and Doppler effect In underwater acoustic hop frequency communication system, every users information is modulated by a special code on the transmitter, the information will be demodulated by the same code at the receiver. The code mentioned here is pseudorandom sequence, the spectrum of the signal will be expanded. Performance of pseudo-random sequence is directly related to system performance, therefore, pseudo-random sequence is a key point of implementing a hop-frequency communication system. This paper is based on the analysis of acoustic communication channel, some common sequences are evaluated, and simulation is made to compare the performance of chaotic sequence and RS sequence.
