| Research Abstract |
Mobility in mobile communication systems changes the state of wireless channels temporally. It is important to construct a communication system that can achieve accurate channel estimation and high-rate data transmission. As a novel scheme to send information for training, a communication scheme based on the bias of the occurrence probability of transmitted symbols has been proposed for multiple-input multiple-output (MIMO) channels, in which multiple transmit and receive antennas are used. Furthermore, two practical schemes have been constructed to realize the bias-based scheme. Numerical simulations show that the proposed schemes can outperform existing schemes.
