Analog SC-FDE using SSB technique
IEICE Communications Express, 2015 In order to improve performance while keeping high spectrum efficiency of analog signal transmission, we recently proposed an analog single-carrier transmission with frequency-domain equalization (analog SC-FDE). In this paper, in order to improve the spectrum efficiency, analog SC-FDE using single sideband (SSB) technique is proposed.
