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.

compress_sensing_without_frame
Compressive sampling is an emerging technique that promises to effectively recover a sparse signal from far fewer measurements than its dimension. The compressive sampling theory assures almost an exact recovery of a sparse signal if the signal is sensed randomly where the number of the measurements taken is proportional to the sparsity level and a log factor of the signal dimension. Encouraged by this emerging technique, this thesis briefly reviews the application of Compressive sampling in speech processing. It comprises the basic study of two necessary condition of compressive sensing theory: sparsity and incoherence. In this thesis, various sparsity domain and sensing matrix for speech signal and different pairs that satisfy incoherence condition has been compiled.
