| 摘 要： | 在块传输系统中，采用预编码—后均衡相结合的联合均衡技术能够有效克服信道的色散效应。本文针对无线信道中三种用滤波器组实现的块传输系统的联合均衡方法，就系统的最大互信息量和误码率性能作了分析比较。理论分析和仿真结果表明，作者提出的MMI—DFEl方法具有最佳性能。 |

| Abstract: | Joint precoding and post-equalization is effective for combating the dispersive effects of channels in block transmission systems. In this paper, we analysis and compare the maximum mutual information (MMI) and bit error rates (BER) of three typical joint equalization methods for block transmission systems implemented by filterbanks in wireless communications. Simulations demonstrate the MMI-DFE1 method proposed by us outperforms the other two methods. |
| Keywords: | joint equalization MMI criterion block transmission systems filterbanks |
