ملخص: In this letter, a multi-phased CDMA system employing a variable spreading gain (VSG) approach is proposed for high-rate applications, based on four algorithms for selecting a multi-code set. From simulation results, in addition to simple receiver structure thanks to level clipping, the multi.phased VSG CDMA system provides an high bit rate transmission, while maintaining an acceptable performance degradation.
