BER Performance Analysis of QAM Modulation Techniques in MIMO Rayleigh Channel for WCDMA System

Wideband Code Division Multiple Access (WCDMA) technology has emerged as the most widely adopted third generation (3G) air interface. 3GPP Release 7 (HSPA+) WCDMA systems introduced two features Higher Order Modulation (HOM) and Multiple Input Multiple Output (MIMO). MIMO improve the throughput in wireless medium. It achieves a higher spectral efficiency. This paper focuses on the performance analysis of 16 QAM and 64 QAM in multiple input multiple output (MIMO) Transmission in the Rayleigh channel by considering two encoding REED SOLOMON Encoding and BCH Encoding in WCDMA system. The analysis has been performed by using MATLAB for simulation and evaluation of Bit Error Rate (BER) for W-CDMA system.
