Bandwidth conservation is an important issue in case of multimedia communication. To alleviate this problem an efficient multimedia communication scheme is proposed in this paper by incorporating wavelet based lossy compressor and a combination of adaptive channel equalizer and an expander at the receiver. The performance of proposed scheme is evaluated by transmitting images at different noise conditions of the channel and by assessing the quality of the image at the receiver. The paper also evaluates the effects of compression ratio (CR), number of bits used in representing the compressed coefficients and the strength of additive noise in the channel. Extensive simulation results demonstrate that the DWT and equalizer based combined scheme outperforms the DCT and ANN based schemes.
