Bit Error Rate Performance Of Orthogonal Codes For Ds-Cdma Multiuser System In Awgn Channel

Abstract
Direct sequence code division multiple access (DS-CDMA) is a popular wireless technology. This system suffers from Multiple Access Interference (MAI) caused by direct sequence users. This paper presents comparative study of BER performance of conventional matched filter using Gold, Hadamard and Walsh code as the spreading sequence. The simulations are conducted in AWGN channel. Keywords- Awgn, Ber, Gold Code, Walsh Code, Hadamard Code.
