块迭代码片均衡算法

Novel block iterative chip equalization algorithms

为了增强码片均衡器的性能,降低运算量,提出了一种 LMMSE 的改进新算法—BILMMSE 算法。理论分析与计算机模拟结果表明 BILMMSE 码片均衡器性能优于传统的 Rake,以及 Griffith 与 MRLS 码片均衡器,与LMMSE 码片均衡器性能基本保持一致,而运算量却大大降低,非常有利于 FPGA 与 DSP 实现。

In order to enhance the performance and reduce the calculation of the chip equalizer, a novel block iterative LMMSE (BILMMSE) algorithm was presented. Theoretic analysis and computer simulations showed that the performance of BILMMSE was superior to conventional Rake, Griffith and MRLS, and close to LMMSE. However, calculation of BILMMSE is much lower than LMMSE’. It proves to have great value in practical applications.
