Abstract

A new asymptotically optimal algorithm for OFDM-signal reception under AWGN and OFDM interference shifted in frequency is proposed. It outperforms the known algorithms in terms of complexity and has no limitations on the number of subcarriers in useful and interfering signals. The proposed optimal reception algorithm can be used for SEFDM signal reception when two components in it are present: the week one for “near to base station” user and the strong one for “far from the base station” user. The complexity of proposed algorithm is investigated.
