| Abstract(in English) | This report proposes a retransmission-subcarrier-block phase hopping (RSBPH) for millimeter-wave MIMO-OFDM systems with subcarrier-block phase hopping (SBPH) and retransmission. The proposed scheme selects the phase rotation pattern to minimize peak to average power ratio (PAPR) among previously unused patterns, and rotates a retransmitted packet by the seleted pattern. Since channels of millimeter wave MIMO-OFDM are quasi-static, the number of retransmitted packets for retransmission systems cannot be reduced. To solve such a problem, the proposed scheme randomizes the channel frequency responses by different phase rotation patterns, which results in increasing the probability of correctly received packets and decreasing both the number of retransmissions and PAPR. Computer simulations demonstrate that RSBPH is superior to MIMO-OFDM and SBPH in throughput performance and evaluate how much PAPR is reduced by RSBPH. |
