The description and performance analysis of a new OFDM/DQPSK signal receiver is considered in this paper. The proposed receiver has performance that is close to the performance for the coherent detection of the OFDM/DQPSK signal, in case of zero carrier frequency offset. In case of non-zero frequency ofset, receiver with decision feedback differential detection (DFDD-OFDM) is often used in the literature. The analysis will show that the proposed receiver has better perfomance in the presence of the frequency offset than DFDD-OFDM receiver, in the sense wider frequency offset range where the error probability is acceptable. The novel proposed OFDM receiver has better performance for all the considered values of the number of OFDM channels.
