| Abstract: | This paper introduces two important technologies on physics layer for broadband wireless access system firstly:one is frequency domain equalization for single-carrier(SC-FDE),the other is multiple-input,multiple-output(MIMO).Furthermore,a system structure combind of SC-FDE and MIMO is built up.Here the emphasis is placed on the research of the frequency domain equalization coefficient and arithmetic of channel estimation and signal noise ratio estimation of this system.At last,simulation results are given to show the performance of this system. |
