Abstract:
1. A method executed in a receiver that includes a first antenna that receives a signal expressible as a vector of signals r 1 , a second antenna that receives a signal expressible as a vector of signals r 2 where signal vectors r 1 and r 2 contain signals transmitted by a first transmitter and signals transmitted by a second transmitter, H 1 is a matrix of transfer coefficients between said first transmitter and said first antenna, H 2 is a matrix of transfer coefficients between said first transmitter and said second antenna, G 1 is a matrix of transfer coefficients between said second transmitter and said first antenna, G 2 is a matrix of transfer coefficients between said second transmitter and said second antenna, and Γ is the signal to noise ratio, comprising the steps of: (1) executing a module for developing an estimate ŝ (a) computing F (b) choosing ŝ and (c) setting Δ (2) executing a module for developing an estimate ĉ (a) computing F (b) choosing ĉ and (c) setting Δ (3) choose pair (ĉ (4) repeat steps (1)-(3) at one more time.
