Özet

Users of mobile IT systems are calling for ever higher data rates, but such mobile radios are subject to multipath fading and intersymbol interference, often calling for complex equalizers at both ends of each link. Where the links are of short range, they often use time-division duplex. This article demonstrates how this option permits much of the complexity of channel matching and equalization to be transferred from post-processing at the many sparsely used mobile terminals to a few intensively used preprocessors at the base station or central hub.
