文中针对TCM分层结构空时分组编码系统,提出了一种新的接收解码方案。该方案首先对接收数据进行线性变换,虚拟的将接收天线个数加倍,然后采用奇异值(SVD)组干抑制方法对信号进行分离。由于提出的新解码方案突破了SVD组干扰抑制技术对接收天线个数的限制,因此可降低接收端的复杂性。仿真结果表明本文提出的解码方案的系统误码性能优于传统组干扰抑制法的系统误码性能。
In this paper, a novel receiving and decoding scheme is proposed for TCM hierarchical structure space-time block coding system. The scheme first linearly converts the received data, virtually doubles the number of receive antennas and then uses a SVD (SVD) group suppression method to separate the signals. Due to the new decoding scheme introduced breaks the SVD group interference suppression technology to limit the number of receiving antennas, thus reducing the receiving end complexity. The simulation results show that the system error performance of the proposed decoding scheme is better than that of the traditional group interference suppression method.
