In this paper we address the problem of how to measure the link quality in terms of signal-to-interference ratio (SIR) over rapidly time varying channels which are due to either fast variation of the interference or the bursty nature of the traffic. We propose a new SIR estimation approach for the UTRA-TDD system, that is based on a pre-selection tentative decision device which discards and selects the estimated symbol on the basis of MAP ratio. Simulation results show that the proposed SIR estimator works well in the context of rapidly time varying channels.
