12.ISCA-RJRS-2013-290
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.

When the P89LPC90x is in programming mode all pins that are not used for programming are tri-stated. During
programming mode the reset pin has a weak pull-up resistor.(When the programming is in a mode 'll pins that are not used for programming are tri- stated. During programming mode the reset pin has a weak pull-up resistor.)
