Abstract :
In this paper, the peak-to-average power ratio (PAPR) properties of m-sequences, 3-term, 5-term and Welch-Gong sequences are discussed as the spreading codes for downlink MC-CDMA. It is shown that for single or multiple users, the orthogonal codes generated by these sequences provide lower peak-to-mean-envelope-power ratios (PMEPR) than Walsh-Hadamard sequences. Therefore, these sequences can be considered as good alternatives to replace Walsh codes by reducing PAPRs of MC-CDMA systems.
