| Abstract(in English) | Recently, we proposed analog single-carrier transmission with frequency-domain equalization (analog SC-FDE) in order to improve performance of analog signal transmission. Analog SC-FDE signal spectrum has a complex conjugate relation between lower sideband (LSB) and upper sideband (USB) since analog signal is real-valued. Exploiting this property, the LSB and USB subcarriers can be combined to obtain an additional frequency diversity gain. In this paper, a subcarrier combining method is proposed for analog SC-FDE. A theoretical analysis of normalized mean square error (NMSE) performance is also presented to evaluate the effect of subcarrier combining and is confirmed by computer simulation. We show that subcarrier combining achieves similar diversity order to 2-branch antenna diversity. In addition, the impact of channel frequency-selectivity on the NMSE performance was also investigated to show the effectiveness of proposed scheme. |
