摘　　要：给出了适用于带宽有限信道的Turbo均衡和译码模型,该模型基于高带宽效率的TTCM译码、软输入软输出均衡器和软输入WRLS信道估计。该模型的均衡器和译码器使用LOG-MAP准则,通过均衡器和译码器间的迭代可以获得更高的增益。This paper introduces a model of joint Turbo - Equalization Channel Estimation and TrCM for bandwith limited channel, This model bases on high bandwith efficiency Turbo -TCM, SISO equalizer and soft input WRLS channel estimater. The equalizer and the decoder use LOG - MAP algorithm. The model has higher gain from the ＂turbo＂ process between the equalizer and the decoder.
