Abstract :
Space-time block coding (STBC) offers a good performance/complexity trade-off to exploit spatial diversity in multi-antenna systems. A particular linear precoder and the Alamouti STBC are combined to improve the space-time diversity using simple linear algorithms. The system presented with four-transmit antennas may be applied to other STBC codes and several antenna configurations.
