Abstract

This paper proposes a new iterative ISI equalization algorithm that offers low computational complexity: order L/sup 2/ with channel memory length L. The proposed algorithm is an extension of D. Reynolds and Xiaodong Wang's SC/MMSE (soft canceller followed by MMSE filter) equalizer (see Signal Processing, vol.81, no.5, p.989-95, 2001): approximations are used properly to reduce the computational complexity. It is shown that the approximations used in the proposed algorithm do not cause any serious performance degradation compared to the conventional trellis-based iterative equalization algorithms.

SC/MMSE迭代均衡器的匹配滤波近似

本文提出了一种新的迭代ISI均衡算法，该算法具有较低的计算复杂度:L/sup 2/阶，信道存储器长度为L。该算法是D. Reynolds和王晓东的SC/MMSE(软抵消器，然后是MMSE滤波器)均衡器的扩展(见Signal Processing, vol.81, no. 1)。5, p.989- 95,2001):适当地使用近似来降低计算复杂度。结果表明，与传统的基于网格的迭代均衡算法相比，该算法中使用的近似不会导致任何严重的性能下降。
