## Abstract OFDM communication system has recently been attracting attention because of its features of high spectrum efficiency and robustness in a multipath environment. The OFDM signal often exhibits a high peak power. It is important to reduce the peak power, since communication quality is degr
In this paper we propose simple schemes which reduce the peak-to-average power ratio (PAPR) of the OFDM-CDMA signals. The statistical behavior of the peak power in the OFDM-CDMA signals is first examined by computer simulations, employing the two orthogonal sets of spreading sequences, namely, Walsh
