Subblock Successive Transform (SST) algorithm is an effective method to reduce the PAPR of the MIMO-OFDM signals, and can fully utilize the degrees of freedom in space domain to overcome the shortage of Successive Suboptimal Cross-Antenna Rotation and Inversion (SS-CARI) algorithm. However, the degrees of freedom in frequency domain are not considered in SST algorithm. For this problem, an improved...
Assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, the distribution of the peak-to-average power ratio (PAPR) in band-limited OFDM signals is investigated in this paper. Based on the level-crossing rate theory, a simple closed-form upper bound on the PAPR distribution of a band-limited OFDM signal is proposed. For the 16QAM-OFDM systems with different...
