OFDM/DPSK System Performance Improvement in the Presence of Frequency Offset using a Reconfigurable Detection Algorithm
AbstractIn this paper we propose a reconfigurable differential detection (RDD) algorithm that can be used for the MDPSK signal reception in the presence of frequency offset. Important feature is that the proposed algorithm does not require pilot symbols, and therefore there is no bandwidth efficiency loss. The analysis shows that the bit error probability of the proposed algorithm is nearly constant in a wide frequency offset range and equal to the error probability for zero frequency offset.
