Abstract:

In this paper we consider a broadband wireless system employing SC (single-carrier) modulations combined with FDE (frequency-domain equalization). We propose a receiver structure for joint carrier synchronization and equalization which combines IB-DFE (iterative block decision feedback equalization) and post-equalization carrier synchronization schemes. The proposed receiver can be regarded as a modified IB-DFE where we perform a decision-directed frequency offset estimation within each iteration of the equalizer. Our results show that the proposed receiver structure has a good performance, allowing BER (bit error rate) close to the MFB (matched filter bound), even with moderate frequency offsets and severe time-dispersive channels.
