Iterative equalization of multipath components whose delay exceeds GI for OFDM transmission

We propose a method that iteratively equalizes the multipath components whose delay exceeds GI in OFDM transmission. A receiver with the proposed method extends GI duration using received signal replicas. The method offers significantly lower computational complexity than the existing method which subtracts inter-carrier interference. Moreover, the proposed method does not degrade FER or BER. We compares these methods in terms of FER and BER performance and complexity.
