This letter proposes a blind channel shortening method for inter-block interference (IBI) suppression in orthogonal frequency division multiplexing (OFDM) systems. In a receiver, there are two OFDM demodulators each with a time-domain equalizer (TEQ) and a frequency-domain equalizer (FEQ). The TEQ parameters are determined such that the outputs of an FEQ are identical to those of another FEQ. It is shown that the proposed method can suppress IBI completely and eliminate the need for channel… CONTINUE READING
