Robust Transmission of Compressed Streams over Land Mobile Satellite Channel at Ku-Band

This paper presents a general framework for the efficient and robust transmission of compressed streams over land mobile satellite (LMS) channel at Ku-Band. Due to the extensive use of predictive coding, compressed data exhibit different sensitivities to transmission errors. Therefore, they are suitable for unequal error protection (UEP) techniques. UEP is mainly based on differentiated error control coding which raises the robustness of data, but also increases the transmission bandwidth. To cope with stringent satellite bandwidth restriction, wavelet packet orthogonally overlapped modulation with unequal power allocation (UPA) is used for UEP of data. UPA is driven by the sensitivities of data to LMS channel errors at Ku-Band.
