摘要

本文提出了一种基于多天线和卡尔曼滤波跟踪的时间选择性衰落信道图像通信系统。我们将刘的方法扩展到2-2天线，并增加了信道编码方法。与无信道编码相比，系统的编码增益可提高约3db。该方案在较低信噪比下提高了系统的误码率(BER);当误码率约为1时。当信噪比大于3db时，接收到的图像可以满足要求。

An image communication system over time varying channels based on multi-antennas and Kalman filter tracking

In this paper, an image communication system is proposed over time-selective fading channels based on multi-antennas and Kalman filter tracking. We extend the Liu's method to 2-2 antennas and add the channel coding method. Compared with the case of a no channel coding, the coding gain of the system can be improved about 3 dB. The proposed scheme improves the performance of the bit error rate (BER) of the system at lower signal to noise ratios (SNR); when the BER is about 1.E-4, and SNR more than 3 dB, the received image can be satisfied.
