Abstract :

In this paper, we propose a new image compression algorithm called improved-ISPIHT, based on wavelet domain method. We apply this algorithm to RS coded FH-SS system for image transmission. Compared to the set partitioning in hierarchical trees algorithm (SPIHT) and modified-SPIHT (MSPIHT), the ISPIHT has better compression efficiency and lower distortion. Simulation results show that the performance of our system is better than those use the standard SPIHT or MSPIHT algorithm.
