Abstract :
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.
