Description
Summary:Channel estimation algorithm is one of the key research directions in UWB systems. For the ECMA368 standard, there is a wave interference problem in channel estimation. This paper constructs a low-order ZP-OFDM-FAST model for improving channel estimation performance. The interpolation problem of virtual zero subcarriers is studied, and the interpolation DFT channel estimation method is proposed. Finally, a method of frequency domain instantaneous filtering is given.
