Claim One:
1. A blind mode equalizer system to recover in general complex valued data symbols from a signal transmitted over time-varying dispersive wireless channels, the system comprising: a channel gain normalizer comprised of a channel signal power estimator, a channel gain estimator and a parameter α estimator for providing nearly constant average power for a normalized output signal and for normalizing a channel with a dominant tap of a normalized channel adjusted to close to 1; a blind mode equalizer with hierarchical structure (BMAEHS) comprised of a level 1 adaptive system and a level 2 adaptive system for equalization of a normalized channel output; and an initial data recovery circuit comprised of a quantizer, a memory, a fixed equalizer for recovery of data symbols received during an initial convergence period of the BMAEHS and pre appending the recovered symbols to a detected symbol output of the BMAEHS providing a continuous stream of all detected symbols.
