Evaluation of Smart Antenna Algorithms for cdma2000 Reverse Link

Abstract

Abstract. Adaptive algorithms which provide desired performance and have small computational load are key factors that enable the integration of smart antennas into 3G wireless communication systems. W e evaluate non-blind (LMS, RLS), blind (CM), and serni-blind (CFA) type receive beamforrning algorithms in terms of their performance, complexity, and convergence rate for cdma2000 systems. Simulations are performed for a 5-element uniform linear array operating in a wireless vector channel that consists of multipaths and multiple access interference. Results show that CF A has the highest SINR with rninimum deviation in varying fading conditions. CM has the smallest SINR performance possibly due to not involving pilot information, but it has the computation Ioad as low as LMS does, i.e. O(M) where M is the antenna number. RLS achieves SINR comparable to CFA with the fastest convergence rate.

“…SINR values for each computed weight vector are calculated as described in [40] and cumulative distributions of the SINR values are obtained. Mean and standard deviation derived from these cumulative distributions are given in Table 5.…”
