Implicit 2D-RAKE function of subband signal processing adaptive array for spread spectrum systems with a spreading code adding a cyclic prefix

摘要

Subband signal processing adaptive array (SBAA) is a promising candidate for realizing high channel capacity under multipath environment having large delay and angular spread in wideband mobile radio systems. SBAA is characterized by its parallel signal processing scheme and less computational load. In this paper, a novel configuration of SBAA with application to spread spectrum systems (or CDMA) is proposed, and the performance, particularly of 2D-RAKE function, is evaluated and identified by computer simulation.
