Method and device for determining smooth window length in channel estimation |
摘要 |
<p>A method and a device for determining a smooth window length in channel estimation is provided. The method includes: obtaining autocorrelation values of pilot signals, where the autocorrelation values include first autocorrelation values and second autocorrelation values, at least two first autocorrelation values exist, and at least one second autocorrelation value exists; determining a speed range according to symbols of the first autocorrelation values or the symbols of the first autocorrelation values and a ratio value between the second autocorrelation value and one of the first autocorrelation values; and determining the smooth window length according to the speed range. Through the method provided in embodiments of the present invention, the problems caused by a fixed smooth window length may be avoided, and this improves system performance.</p> |
