Abstract
While the performance of direct sequence spread spectrum systems have been studied extensively, the effect of nonlinearities on system performance has received limited attention. This paper addresses the performance of direct sequence spread spectrum systems employing a nonlinear amplifier. Inter-modulation products due to nonlinear amplification are analyzed and the effect of nonlinearities is illustrated by means of a simulation result. In the simulation a third-order nonlinear amplifier is used to represent the nonlinearity. Third-order inter-modulation terms which fall in the desired signal frequency band are shown to degrade system performance.
