采用T.Chan的总体变分(TV)方法实现图像修复，由于算法本身的局限性，无法解决视觉连通性的问题。(using T. Chan of the overall variation (TV) method of image restoration, Due to the limitations of their own algorithm to solve visual connectivity problems.)

Application of spread spectrum for satellite land mobile systems is difficult in satellite link because of synchronization and providing code or considerable Doppler shift. This is particularly high for LEO satellites. So that, a Doppler shift carrying a frequency in band S can reach to several tens of kHz. To estimate and compensate Doppler, a CW pilot carrier is used. The aim of this study is simulate Doppler frequency estimation using MIMO-OFDM technique. Finally, the proposed algorithm is compared to MMSE algorithm in order to insure its performance.
