Protection of a QPSK Communication System with an LMS Adaptive Array.

Abstract

The performance of a quadrature phase-shift-keyed (QPSK) communication system which uses an adaptive array is examined. The equations that describe the adaptive array and ideal detector performance are derived for the case where the desired signal is corrupted by CW interference. Performance calculations are described which show that the adaptive array offers a significant degree of protection from this type of interference. The effects on performance of the signal frequencies, power levels, arrival angles and the array bandwidth are examined. (Author)
