Description: This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station,
with a constant speed such that the Maximum Doppler frequency is 5 Hz. The element spacings at the base station and mobile are one lambda and 0.5 lambda, respectively. The maximum angle spread at the base station is 4 degrees, whereas isotropic scattering is assumed around the mobile. The length of the simulated MIMO channel is 5 seconds, and any two adjacent samples are spaced by 0.01 seconds. For ensemble averaging, 90 realizations of the MIMO channel are generated.-This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station, with a constant speed such that the Maximum Doppler frequency is 5 Hz.

Description: 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. Platform: |
