An Insight into the Estimation of MIMO Propagation Parameters using the Sage Algorithm

In this contribution, we provide a thorough review of the application of SAGE (space-alternating generalised expectation-maximisation) algorithm to the problem of parameter estimation for MIMO (multiple-input multiple-output) systems. It is well established that the SAGE algorithms yields a superior performance compared to other estimation algorithms in terms of accuracy and robustness. For our investigation, we consider both the time and frequency domain evaluations of the algorithm since each domain requires a different signal model.
