摘要：

OFDM-based broadcasting systems such as DVB-T2 offer an excellent opportunity to obtain channel sounders at low cost and low complexity. However, there is an uncertainty in the phase measurements that should be removed to obtain reliable results. This paper proposes a channel phase calibration using Savitzky-Golay in the time domain. Channel State Information (CSI) vectors, like those obtained with OFDM-based receptors, have been simulated with the Typical Urban model (TU6) as the golden standard. The numerical results significantly improve the phase calibration concerning the reference method.
