Abstract :
A novel beam-forming detector for group space-time coded systems is proposed in this paper, which utilizes unitary preprocessing in the transmitter to simplify the decoding complexity in the receiver. Eigenmode selection is introduced to achieve more system diversity gain. Furthermore, a simple example for variable-rate group space-time coded systems is presented. Simulation results show that the proposed detecting algorithm has better BER performance with lower decoding complexity.
