POWER DELAY PROFILE (PDP) ESTIMATION METHOD AND DEVICE

摘要

Disclosed are a power delay profile (PDP) estimation method and device, used for improving accuracy of PDP estimation. The method comprises: acquiring time-domain channel estimates of pilots; obtaining an average time-domain channel estimate according to the time-domain channel estimates of the pilots, determining an effective path according to the average time-domain channel estimate and a preset threshold, and determining a position number of the effective path in the number of points of fast Fourier transform (FFT) for performing orthogonal frequency division multiplex (OFDM); and determining a power delay profile (PDP) according to the effective path and the position number.
