Performance analysis of WCDMA
Abstract In Universal Mobile Telecommunication System (UMTS), high data rate transmission is possible by using Wideband Code Multiple Access technique (WCDMA) as an air interface. This paper studies performances of various modulation schemes such as Phase Shift Keying(both BPSK and QPSK) and 16 – Quadrature Amplitude Modulation (16-QAM) in WCDMA downlink transmission to improve its data rate. Performance analysis of WCDMA Based on Bit Error Rate (BER), performances of various modulation schemes have been investigated. The Simulation tool Matlab R2013a is used for simulation of WCDMA system implemented with QPSK, BPSK and 16-QAM modulation techniques and we are going to analysis BER vs SNR for all modulations.
