Error resilient transmission of SPIHT coded images over fading channels

The paper introduces a method of transmitting error resilient SPIHT coded i mages over highly error prone Rayleigh fading channels. First, the source s ignificance of the SPIHT coded output is obtained. Based on the significanc e of the bits, the channel coding is varied accordingly. Channel coding con sists of a mixture of rate compatible punctured convolutional (RCPC) codes and interleaving to combat the burst errors produced by the fading channel. An additional error concealment technique is also introduced into the SPIH T decoder to improve its results in cases where errors cause the corruption of the average luminance level during decoding. Comparison with using RS b lock codes at a total transmission rate of 1.0 bits/pixel is carried out ov er fading channels with very high error rates to show the superiority of th is method over methods using burst error codes.
