Abstract

A covariance-based algorithm is proposed to find the interference blocking filter for single-input multiple-output orthogonal frequency division multiplexing (SIMO OFDM) systems. The algorithm uses only the auto-covariance matrix of the received signal. It does not require precise carrier synchronization and time synchronization, so it is applicable to an environment with uncooperative high power interferences
