Since adaptive equalization in time domain proved oftentimes to be a too expansive solution in terms of computational complexity and implementation costs, some different equalization approaches must be considered. In this paper we shall investigate the performance of two recent-years findings in this direction, i.e. OFDM (Orthogonal Frequency Division Multiplexing) and SC-FDE (Single Carrier with Frequency Domain Equalization).
