Multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) has attracted much attention as a solution of high-quality service for next generation wireless communications. However, like OFDM, one of main problems of MIMO-OFDM is the high peak-to-average power ratio (PAPR). In this paper, a novel method to reduce the MIMO-OFDM PAPR is proposed. This method applies space...
One of the major disadvantage of OFDM is the high peak-to-average power ratio (PAPR) of the transmitted OFDM signal. This paper proofed the autocorrelation properties of CAZAC sequence, and then proposed a new method to reduce the PAPR in OFDM systems based on CAZAC sequence by taking advantage of the low autocorrelation characteristics of CAZAC sequence .This scheme expands the conventional OFDM...
