AB  - CDMA has become the   focus of current research interests to provide higher data rates for end users and to accommodate more users over wireless channels in the next generation communication systems having 3G standard and 4G standard. Two important features of CDMA systems are the use of complex spreading and user dedicated pilot channel. This CDMA system uses QPSK since it is one of m-ary keying systems intended for bandwidth reductions. The performance this system gets s affected by many factors in the channel. This can be done by efficient FEC scheme. This study proposes a novel FEC scheme, which reduces BER and hence improves the performance of the CDMA system
