Abstract
A covariance matrix based anti-interference algorithm is proposed for SIMO OFDM systems. This algorithm constructs the interference-blocking filter without the information of the inferences. This algorithm is insensitive to the time synchronization error and to the carrier frequency synchronization error. Therefore, it is especially useful for the case when interferences are strong and unknown, such as the case in the unlicensed spectrum.
