Due to the extensive use of predictive coding, multimedia compressed streams exhibit different sensitivities to transmission errors. Therefore, they are suitable for unequal error protection (UEP) techniques which aim at preserving the integrity of sensitive data. UEP is mainly based on differentiated error control coding which raises the robustness of data, but also increases the transmission bandwidth. However, the design of efficient wireless communication systems is often complicated by stringent bandwidth constraint. This work proposes a general framework for efficient and robust transmission of multimedia compressed streams over band-limited wireless channels. To cope with bandwidth restriction wavelet packet orthogonally overlapped modulation with unequal power allocation (UPA) is used for UEP of data. Performance is tested over AWGN and frequency flat Rayleigh�s slow fading channel, which well model the transmission conditions typical in most wireless communication standards such as WiFi and Bluetooth.
