Abstract
This paper describes the integration of an LMS adaptive array into a pseudonoise (PN) coded biphase modulated communication system. The paper explains how these systems my be combined and presents a systems overview of the interaction between the adaptive array and the signaling waveform. An experimental system is described, and typical performance results are presented. The hybrid system requires only very modest spectrum-spreading ratios, such as 5:1, for the adaptive array to null interference. The combined system provides the interference protection of the adaptive array during the code timing acquisition phase as well as after code lockup.Keywords
