Abstract

We propose an unbiased, computationally efficient estimator of the scattering function that is specifically suited to underspread WSSUS channels. The novel estimator allows for nonideal sounding signals, fast time-variation, and on-line operation during data transmission. Its good performance is assessed by a bias/variance analysis and simulation results
