Abstract :
During the process of acquisition, a spread spectrum system is at its most vulnerable stage, since it has no processing gain working in its favor. In this paper, a narrowband interference suppression filter is used to enhance the performance of a serial search acquisition scheme for a direct sequence spread spectrum receiver. An analytical expression for the probability of error is presented, and numerical results are used to illustrate the sensitivity to various system parameters.
