Abstract:
1. A receiver comprising: a detector of space-time coded signal; and a decoder for decoding a channel code encoded signal that is embedded in output signals of said detector, where said detector receives a signal, via a first and a second antenna, from a first transmitting unit and a second transmitting unit, and decodes using a two step algorithm expressed by: where r 1 is a vector of signals received at said first antenna, r 2 is a vector of signals received at said second antenna, H 1 is a matrix of transfer coefficients between said first unit and said first antenna, H 2 is a matrix of transfer coefficients between said first unit and said second antenna, G 1 is a matrix of transfer coefficients between said second unit and said first antenna, G 2 is a matrix of transfer coefficients between said second, and Γ is the signal to noise ratio.
