METHOD AND DEVICE FOR MONO- AND MULTI-ANTENNA RECEPTION FOR ALAMOUTI-TYPE LINKS

摘要

The invention relates to a method and system for separating multiple users in a communications system that includes two transmitting antennas and one to N receiving antennas, said signals transmitted by said users containing the symbols an, x() corresponding to the vector of the envelopes of the output signals from 1 to N receiving antennas after a shaping filtering operation, characterized in that said vector uses a linear filter, a root mean square, extending over an extended observation vector x = [x(2n-1)t x(2n) t x(2n-1)H x(2n) H] t where x(2n-1) and x(2n) correspond to observations (Nx1) (N=1) at symbol instants 2n-1 and 2n.
