Abstract
The performance of the WCDMA system is degraded due to the various network impairments such as interference, fading & noise and also due to network load. The work in this presents performance analysis of zero forcing successive interference cancellation (ZF-SIC) scheme for the multiuser detection in the WCDMA environment. The bit-error rate (BER) of WCDMA using ZF-SIC for binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK) has been analyzed. The ZF-SIC scheme subtracts the strongest received signal from the original one by one till all users have been detected and demodulated. The proposed scheme also suppressed multiple-access interference (MAI) and improved the system performance significantly. The simulation results showed that the BER is decreased the with number of users increased
