首发时间:2009-12-29
摘要:在传统的无线通信系统中,接收机各个子模块只前向传递信息,这种直线的信息处理方式会因损失有用软信息而造成性能下降。基于Turbo迭代思想的联合迭代检测译码算法联合处理检测器和译码器,经过循环迭代后,系统可以充分利用检测器的软信息和信道译码器的软信息。仿真结果表明,经过一定次数的循环迭代之后,系统能取得高性能增益。

Iterative Joint Detection and Decoding with High Performance
Abstract:In the traditional wireless communication systems, all the modules of the receiver just transmit the information in a straightly forward direction, which will result in losing the soft information and reducing the system performance. The iterative joint detection and decoding algorithm (IJDD), derived from the Turbo coding, takes advantage of the soft information of detector and decoder and enhances the performance by iterative processing. Shown in the simulation results, the system can receive high performance by several iterations processing with IJDD algorithm.
