Abstract:

A novel timedomain overlapped single-carrier(SC) broadband scheme OVSC was proposed to improve the spectrum efficiency of the SC transmission system. The spectrum efficiency, the performance, and the peaktoaverage power ratio of the scheme were studied. A suboptimum detection algorithm(J-FDE) based on the frequency domain equalization(FDE) was developed and the soft output iterative FDE algorithm JI-FDE was studied. The pilot design and the frame structure were investigated for the proposed OVSC-FDE scheme. The simulation demonstrated that the performance of the OVSC-FDE is better than that of the OFDM and SC-FDE using the multi-level modulation at the same spectrum efficiency.

Key words: information processing, single-carrier(SC) transmission, frequency domain equalization (FDE), time-domain overlap, spectrum efficiency
