中文摘要：
提出了频选衰落信道下基于GF（q）的LDPC编码系统的Turbo均衡，将性能优异的q-LDPC码作为外码，以信道响应作为内码构成级联结构，在接收端采用迭代的方式实现数据的高性能检测。相比卷积编码作为外码的Turbo均衡有2dB的性能改善，提高了误码性能。
英文摘要：
A Turbo equalizer based on LDPC coded on GF（q） over frequency selective fading channels is proposed in this paper. In such a case,it can be view as a serially concatenated structure in which the q-LDPC coder is used as outer-code and~ the channel expanded serve as inner code.At the receiver,the iterative detection algorithm is presented.Simulation results show that the scheme yields tremendous improvement and outperforms the convolution coded Turbo equalizer 2 dB.
