Abstract(in English) | In this paper, we propose space-time codes for 256-quadrature amplitude modulation (QAM) with two transmit antennas. Firstly, we introduce a matched mapping method by the ring of integers to easily calculate the distances between any pairwise codewords. Then we calculate the trace and product values of all possible space-time codes, and compare with the bit error rate (BER). As the results, we propose two types good space-time codes. The error rate performance of the two types proposed codes are compared with that of the Alamouti code by their several properties and BER computer simulations. These results show the proposed codes almost outperform the Alamouti code when the number of receive antennas is more than one, and the increased number of receiving antennas with our code is a decided advantage. |
