PAPR Reduction of an MC-CDMA System through PTS Technique using Suboptimal Combination Algorithm
نویسندگان
چکیده
Multicarrier Code Division Multiple Access is the most promising technique for high speed data transmission. However, the MCCDMA signals are characterized by large peak to average power ratios (PAPR), which can reduce the system efficiency. In this paper PAPR reduction of an MC-CDMA system using PTS technique is investigated by using suboptimal combination algorithm, which uses binary phase factors, for BPSK and QPSK modulation techniques at different number of active users. The results show that BPSK is a more effective modulation scheme for PAPR reduction in MCCDMA system.

This paper analyzes the Peak-to-Average Power Ratio (PAPR) problem in Multicode-Code Division Multiple Access (MC-CDMA) systems. The statistical distribution of PAPR is derived and the achievable PAPR reduction for a given code rate is estimated.
