| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In MU-MIMO THP, the ordering process is effective to improve the transmission performance. However, the ordering process causes a large amount of computational effort especially in application to OFDM. This is because this process has to be conducted in each subcarrier. To cope with this problem, we propose an efficient ordering calculation method employing frequency correlation. The basic idea behind this proposal is that the ordering results are considered to be the same among the neighboring sub-carriers in relatively small delay spread. Moreover, the frequency correlation is theoretically obtained from the delay spread which is determined by the instantaneous impulse responses of multiple transmit antennas. The effectiveness of the proposed method is demonstrated in terms of calculation cost and the bit error rate (BER) by comparing with the traditional MU-MIMO-OFDM THP without thinning. | |
