Abstract (in Japanese) (See Japanese page) 
(in English) This report proposes subcarrier-block phase hopping applied to the MIMO-OFDM transmission that employs the subcarrier phase hopping for space division multiplexing (SPH-SDM). The proposed method can reduce peak-to-average power ratio (PAPR) and improve BER performance by dividing the subcarriers into some blocks and rotating the phase of the complex time-domain signal which IFFT generates from the sucarriers of each block. As a conventional PAPR reduction method, the partial transmit sequence (PTS), which divides the subcarriers into some blocks and rotates the phase of the time-domain signal converted from the blocked subcarriers by IFFT, has been proposed. This report enhances PTS such that it can be applied to SPH-SDM, which derives the proposed method that can simultaneously achieve PAPR redution and improvement of BER performance. In additon, the method uses the phase rotation with the four phases ($0, \pi/2, \pi, 3\pi/2$) , which is realized by reversing the sign and then can reduce the numerical complexity. Computer simulations compare the proposed method with a conventional one , the enhanced selected mapping (ESLM) which performs the subcarrier phase hopping for the modulation signal before IFFT, with respect to both PAPR performance and the numerical complexity. It is demonstrated that proposed method can achieve the almost same PAPR as that of ESLM with a half of the complexity of ESLM.
