Abstract :
The paper derives analytical Cramér-Rao bound expressions for the Doppler-Angle estimators used in multiple-input multiple-output (MIMO) communication systems. Our motivation is two folds. First, these analytical expressions are used as a measure of the optimal performance that an Angle-Doppler MIMO estimator can potentially achieve. Second, we illustrate the potential of improvement with the time reversal (TR) coupled MIMO Angle-Doppler estimator over its conventional counterpart. In our Monte Carlo simulations, the proposed TR/MIMO communication system provide gains of up to 5dB.
