An Improved Channel Estimation Algorithm for OFDM UWB
Channel estimation is very important for OFDM based UWB system because of its coherent demodulation. In this paper, a new improved channel estimation method is proposed based on the characteristics of the UWB channels. Compare with the estimator using discrete Fourier-transform, the proposed algorithm can properly choose suitable length of time-domain filter by distinguishing different channel conditions. It is shown by simulation that better performance can be achieved especially for IEEE cm1 and cm2 channels.
