Method of symbol detection for MIMO dual-signaling uplink CDMA systems
The invention provides a block-wise successive interference cancellation (SIC) detection algorithm for a general multi-input multi-output (MIMO) CDMA system over the frequency-selective channels, in which each user's data stream can be simultaneously applied with orthogonal space-time block encoding for transmit diversity or spatially multiplexing for high spectral efficiency according to the channel conditions. For such the considered dual-signaling system, the receiver could suffer from the large dimension data processing. A two-stage approach for block-wise SIC detection algorithm is thus proposed to further reduce the computational complexity.
