Abstract (in Japanese) (See Japanese page) 
(in English) Under interference channels with multiple transmitters simultaneously transmitting through the same frequency and time, mutual interference should be handled since it deteriorates the overallperformance of the network. Semi-blind interference alignment (S-BIA) can achieve high degrees-of-freedom (DoF) by multiplying the alignment coefficients (AC) by information signals at transmitter side. However, S-BIA may lead to significantly high transmit power due to the channel inversion of ACs, which results in a considerable penalty under average transmit power constrained scenario. In this paper, A clipping technique for each AC tomitigate the penalty of transmit power is considered. Althogh the proposed clipping improves the overall performance of S-BIA, error floor of bit-error rate (BER) may arise due to the nonlinear distortion. performance of S-BIA is evaluated via computer simulations and investigated the optimal clipping value.
