Abstract

Recently, Wideband Code Division Multiple Access (WCDMA) technology has emerged as the most widely adopted third generation (3G) air interface. Conventionally, the Pseudo random Noise (PN) sequence and gold code sequence are used as spreading codes in WCDMA. However enhanced performance using these sequences is achieved by increasing the length of the sequence. In this paper, Bit Error Rate (BER) performance of WCDMA is determined and analyzed by considering various spreading codes of affordable spreading factor in the presence of Rayleigh channel with AWGN. The performance of WCDMA system using Walsh Code is also compared with other spreading sequences such as PN and gold sequence for various Spreading Factors (SFs). However, simulation results show that the BER of WCDMA can be improved drastically by using Walsh code.
