| 摘 要： | 针对基于编码的MIMO-OFDM系统提出了一种迭代信道估计接收技术.接收机首先通过导频对信道进行估计,然后通过解调译码输出判决信息对信道参数进行更新.仿真结果表明,在高信噪比环境下,可显著地降低系统的误码率. |

| Abstract: | An Iterative receiver with channel estimation for coded MIMO-OFDM systems is proposed. Channel Parameters are firstly estimated with the aid of pilot symbols. After turbo demodulation and decoding, robust channel estimations are refined using hard decision feedback from the decoder. The error floor of the system can be reduced significantly for the case of high SNR. |
