Reduction of PAPR through PTS Technique in MC-CDMA

The most favorable technique for high speed data transmission is Multicarrier Code Division Multiple Access. The MC-CDMA signals, which are characterized through PAPR, which can reduce the efficiency of the system. In this paper, we have to reduce the PAPR of an MC-CDMA system using PTS (Partial Transmit Sequence) through suboptimal combination algorithms(BPSO&BFO), which uses binary phase factors, for different number of active users and for different modulation techniques.
