Abstract

We analyze the performance of single carrier transmission with frequency domain equalizations (SC-FDE) over UWB communications with least-square (LS) channel estimation. The probability density functions (PDF´s) of the frequency domain minimum mean-squared error (MMSE) equalizer taps are derived. The error probability of SC-FDE over UWB channels with LS channel estimation is presented and evaluated numerically. Simulation results validate the use of Gaussian approximation method in the performance analysis of the SC-FDE system with LS channel estimation.
