Description
Summary:In this paper, we develop a new design for adaptation of linear dispersion code. A new adaptive parameter called spacetime symbol rate is applied in our design. We have studied the statistics of signal-to-interference-noise of a linear MMSE receiver over a Rayleigh fading channel. The average BER for a given constellation using the MMSE receiver is calculated numerically. With the statistics as a guideline, two adaptive techniques using constellation and space-time symbol rate are studied, respectively. If constellation and space-time symbol rate are considered jointly, more selection modes can be available. Theoretical analysis demonstrates that the average transmission rate of the joint adaptation can be improved in this case. Simulation results are provided to show the benefits of our new design.
