A new transmit diversity method based on waterpouring principle in multiple antennas systems

We propose a new transmit diversity method which combines Fast Frequency Hopping and MIMO technologies. This transmit diversity method could provide full spatial diversity in multiple antennas systems under the assumption that the transmitter has known the channel state, and it could bring frequency diversity gain at the same time. In this method, a judicious design of frequency hopping pattern allows the receiver the down converts the signals transmitted via one down converter. Then we evaluate its performance in fading environment through Monte Carlo simulation and compared it with common diversity methods. Results show that this new method functions effectively in combating fading and noise.
