| Abstract(in English) | The single-carrier (SC) transmission performance significantly degrades due to inter-symbol interference (ISI) in a severe frequency-selective fading channel. We have proposed a joint use of Tomlinson-Harashima (THP) and frequency-domain equalization (FDE) and evaluated the bit error rate (BER) performance by computer simulation. In our proposed scheme, we define the composite of the propagation channel and FDE as the equivalent channel. Since this equivalent channel is the non-causal filter, THP can not be used directly. We apply QR-decomposition to the equivalent channel gain matrix after FDE to transform the equivalent channel into the causal channel so that we can apply THP to suppress the ISI. So far, we have evaluated the BER performance improvement achievable with a joint use of THP and FDE by computer simulation only. In this paper, we develop a theoretical foundation for the joint THP and FDE. We derive the conditional bit error rate (BER) for the given set of channel gains in a frequency-selective Rayleigh fading channel. We evaluate the average BER performance by Monte-Carlo numerical computation method using the derived conditional BER. The theoretical analysis is confirmed by computer simulation of the signal transmission. |
