Abstract
Joint mitigation of time- and frequency-selectivefading is an important and challenging problem in mobilecommunications. Relying on transmitter-induced redundancy,we propose novel channel estimation and symbol recovery approachesfor blind identification and equalization of timeandfrequency-selective channels, where the time variation is modeleddeterministically by a basis expansion. The resulting statisticalalgorithm enables the usage of a single antenna, dispenses withchannel...Keywords
