摘要：

A new algorithm for reducing peak-to-average power ratio (PAPR) of multicode code division multiple access (MC-CDMA) systems under binary PSK modulation is presented. The algorithm is based on Reed-Muller (RM) codes that are modified by finding a suitable binary sequence that minimises the PAPR of the MC-CDMA. Three types of RM codes are investigated: namely, zero order, first order and second order. Simulation studies conducted show that the proposed algorithm achieves transmitter power savings of up to 6 dB. Zero-order and first-order codes exhibit 0 dB PAPR, while several others maintain a constant and low PAPR as compared with the original MC-CDMA systems.
