这篇文章在频率上为块传播建议一种多级式的软决定均等(SDE ) 技术选择多输入多产量(MIMO ) 隧道。用 Toeplitz 结构,一般信号模型能被变换成一系列小型的亚信号模型。为每个亚信号模型,软干扰取消(原文如此) 第一被使用移开介入的符号的部分效果,然后, max-log-map 范围解码器被执行得到需要一个 posteriori 信息。模拟证明与更低的复杂性,建议方法超过概率数据协会 SDE 和 Schnorr-Euchner 范围解码器。
This article proposes a multistage soft decision equalization (SDE) technique for block transmission over frequency selective multi-input multi-output (MIMO) channels. Using the Toeplitz structure, the general signal model can be converted into a series of small-sized sub-signal models. For each sub-signal model, soft interference cancellation (SIC) is used firstly to remove partial effects of interfering symbols, then max-log-map sphere decoder is performed to get the desired a posteriori information. Simulation shows that with lower complexity the proposed method outperforms the probability data association SDE and the Schnorr-Euchner sphere decoder.
