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. |
