CHOS-based channel tracking in cellular TDMA communications
M. Martone · 2002
The channel tracking problem in the reverse link of a TDMA cellular system exploiting cyclostationary higher order statistics (CHOS) is studied. An adaptive algorithm based on fourth-order cyclic cumulants of the fractionally spaced baseband received signal is derived. The algorithm reveals from experimental verification improved performance with respect to the traditional MMSE method.
