Abstract

This paper considers an UWB (ultra-wideband) SC-FDE (single-carrier input-multiple output with frequency domain equalization) system for multiuser. The method exploits higher order statistics (HOS) in the received signals. It is followed by a method which solves permutation problem. The permutation problem is caused by the Fourier transform (FFT) operations. Simulations show that the proposed method performs close to the equalizers with perfect channel knowledge at the receiver
