  Abstract

In this paper, Discrete Fourier Transform spreading Single Side Band Windowing and Restructuring-OFDM(DFT spreading SSB WR-OFDM) system using DFT spreading SSB method and WR-OFDM system simultaneously is constructed and evaluated its performance. In order to transmit the number of bits to be transmitted more than the OFDM method in which SSB symbols are transmitted by applying the existing DFT operation, (2N-2) -point DFT operation is applied to generate an SSB symbol. The BER (Bit Error Rate) performance and the spectral efficiency of the DFT spreading SSB WR-OFDM system using 4-PAM, 8-PAM, 16-PAM are almost same conventional 16-QAM, 64-QAM, and 256-QAM system. DFT spreading SSB WR-OFDM system exhibits an out-of-band(OOB) power characteristic that is about 27 dB lower than that of the conventional OFDM system.
