Abstract:
1. A receiver having a first antenna and a second antenna comprising: a detector responsive to an input signal from said first antenna and from said second antenna, where the input signal includes a first signal from a first transmitting unit and a second signal from a second transmitting unit that is synchronized with said first transmitting unit, where said first signal and said second signal are each encoded employing channel coding, followed by space-time coding; and a decoder for channel code decoding of output signals of said detector; where said detector identifies information symbols embedded in the input signal by choosing symbols ĉ where, {tilde over (r)}=[r 1 T r 2 T ], r 1 is the signal received by said first antenna and r 2 is the signal received by said second antenna, α* 1 =M −1 h 1 , α* 2 =M −1 h 2 , M is substantially equal to HH*, h 1 is a first column of H, h 2 is a second column of H, h ij is transfer function from j th transmitting antenna of said first transmitting unit to i th receiving antenna of said receiver, and g ij is transfer function from j th transmitting antenna of said second transmitting unit to i th receiving antenna of said receiver.
