摘要：This paper addresses power allocation methods for multimedia signals over wireless channels. The aim ofthis paper is to minimize total power allocated for image compression and transmission, while the powerfor each bit is kept at a predetermined value. Maximum and minimum power control algorithms areproposed. In this work, an approach for minimizing the total power allocated to a multimedia like imagedue to source compression and transmission subject to a fixed bit source distortion using differentparameters are analysed. Simulations are performed using haar wavelet over AWGN channel. StructuralContent (SC), Average Difference, Normalized Absolute Error (NAE), etc are analysed. Maximum PowerAdaptation Algorithm shows better performance than Conventional Power Adaptation Algorithm.
