Abstract :
This paper presents an equalization of SC-FDMA systems without any reference symbols by using a FD-DFE. The Aim is to avoid the loss of spectral efficiency and throughput due to the reference symbols encountered in the existing SC-FDMA systems. Unfortunately, this equalizer shows adapting problems to the SC-FDMA context concerning conversion of circular to linear convolution that we´ll try to overcome by proposing two solutions.
