Abstract

M-ary spread spectrum telemetry is employed to overcome the constraints imposed by spreading factor in data rate. In this paper, M-ary spread spectrum code division multiple access (CDMA) underwater acoustic (UWA) communication is proposed to improve data rate of conventional CDMA, and the data rate enhancement of M-ary CDMA is investigated. The performance of the conventional and proposed schemes over sloping sea channel with additive white Gaussian noise has been evaluated. The effect of multiple user interference (MUI) is investigated through analytical expressions and simulation to exhibit the characteristics of the proposed scheme. Numerical results and comparison of the two methods in terms of equal data rate are also given.
