COFDM

The program is about buck converter PWM in simulink.

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.
