Original Abstract

In this paper, we propose an OFDM receiver which uses an improved decision-feedback differential detection algorithm (DFDDI-OFDM) that can be used for the MDPSK signal reception in the presence of frequency offset. Proposed scheme is compared with OFDM receiver which used an rdinary decision feedback differential detection (DFDD-OFDM) receiver. The analysis shows that the symbol error probability of the proposed algorithm is nearly constant in a wide frequency offset range and equal to the error probability for the zero frequency offset. It should be noted that the roposed algorithm has the same complexity as the referenced receiver.
