Abstract :
In this paper, cyclostationarity of the V-BLAST MIMO OFDM signal is examined based on the model of MIMO OFDM systems in the wireless communication channel and the theory of cyclostationarity. Mathematical deduction and simulation results are both shown that the received MIMO OFDM signals is cyclostationary in the wireless communication channel. Meanwhile, if the received signal is sampled at the data rate, a cyclostationary sequence can be obtained. And if the received signal is oversampled, then a cyclostationary sequence with its cyclic period magnified along with the oversampled rate.
