Abstract
Wide Code Division Multiple Access (WCDMA) offers global mobile multimedia communication capabilities by supporting high bandwidth and data rate up to 2 Mbps at chip rate of 3.84 Mcps and 5 MHz bandwidth. But the performance of the WCDMA system is degraded with various factors such as Interference, fading and scattering. The work in this paper analyzed the effect of Zero Forcing Successive Interference Cancellation (ZF-SIC) for quadrature phase shift keying (QPSK) and binary phase shift keying (BPSK) in WCDMA system. The ZF-SIC scheme is less complex and gives better performance as compared to other interference cancellation schemes. The ZF-SIC scheme is analyzed at the varying values of various parameters of Root Raised Cosine (RRC) filter. The results are obtained in terms of improvement in the Bit error rate (BER) at different values of signal to noise ratio (SNR). The simulation results indicated significant improvement in the signal quality of WCDMA system.
