U - SHAPE architecture for optimal MUD. Exploits selective updating in which L updating processors are shared among M channels (L << M).
	Equalization: SM-linear equalization, SM-DFE.
	Linear Multi-user detection (MUD): Adaptive SM-MUD, Blind MUD.
	Interference Cancellation: Non linear MMSE parallel interference cancellation.
	Channel Estimation & Tracking: Multipath channels for CDMA & non-CDMA systems.
	Adaptive Arrays: Beamforming for CDMA & OFDM.
	Space-time processing: Combined array processing & MUD.
