| Summary: | 碩士 === 中原大學 === 電子工程研究所 === 98 === In this paper, we consider a wavelet domain diversity combining method for image transmission under partial band noise jamming (PBNJ). We propose a new image compression algorithm called modified-SPIHT (MSPIHT). Compared to the set partitioning in hierarchical trees algorithm (SPIHT), the MSPIHT is more appropriate for unequal error protection technique (UEP). Besides, our system considers a diversity combining to improve the received image quality for fast frequency-hopping (FFH) system to resist the jamming. Simulation result shows our MSPIHT algorithm not only has better compression reconstruction image quality, but also has better performance better than that use standard SPIHT algorithm with or without selective diversity combining method.
