| 摘 要： | 利用子载波间相关性对V-BLASTOFDM系统各子信道矩阵进行预处理,可有效降低信号检测算法的复杂度。利用分组排序的思路,在已知与未知信道延时功率谱部分参数两种情形下,分别提出了适用于V-BLASTOFDM系统信号检测的实用分组估算方法,并通过仿真证明了该方法的合理性。

| Abstract: | Preprocessing the subchannel matrices of V-BLAST OFDM systems by utilizing the correlation of subcarriers is an efficient way to reduce the complexity of signal detection algorithm.The idea of packet sequencing being used,practical methods of grouping estimation are presented respectively in the two cases of known and unknown partial parameters of channel delay power spectrum.Simulation results show the rationality of the method. |
