Abstract  Abstract

MULTI-MODE TERMINAL IN A SPACE MULTIPLEXING MIMO WIRELESS SYSTEM. A user terminal supports multiple spatial multiplexing (SM) modes such as one directed mode and one non-directed mode. For data transmission, multiple data streams are encoded and modulated according to their selected rates to obtain multiple data symbol streams. These streams are then spatially processed according to a selected SM mode (e.g., by a matrix of directed vectors for the directed mode and with the identity matrix for non-directed mode) to obtain multiple transmission symbol streams for transmission from multiple antennas. For data reception, multiple received symbol streams are spatially processed according to the selected SM mode (for example, by a matrix of eigenvectors for directed mode and a spatial filter matrix for non-directed mode) to obtain multiple symbol streams of recovered data. These streams are demodulated and decoded at their selected rates to obtain multiple decoded data streams.
