Abstract :
In this paper, a new fast error resilient entropy coder (FEREC) for robust image transmission over wireless fading channels is proposed. A slow, frequency non-selective Rayleigh fading channel model is used. The proposed FEREC algorithm is observed to be almost twice as fast as EREC in encoding the data and hence the error resilience capability is also significantly better. Up to 2 dB improvement in the peak signal to noise ratio of the received image is achieved when compared to EREC
