  • Abstract
    This paper puts forward an improved channel parameter estimator based on the level crossing rate (LCR) computation and double sampling rate (DSR) signal processing, where the appropriate sampling rate is studied by the numerical computation. Subsequently, by exploiting the selected sampling rate, we can estimate both the Doppler shift and the signal-to-noise ratio (SNR) with a high accuracy. Extensive simulations explicitly show a good performance for the proposed algorithm.
