A Method to Improve the Demodulation Speed of Digital Signal
Jing He, Yang Liu · 2017
In this paper, the DSTFT algorithm is optimized from the point of view of improving system demodulation speed.For the sliding windowing process, this paper gives two fast implementation schemes of DSTFT -recursive and code-sliding.The recursive algorithm of rectangular window and all -pole window is introduced in detail, and their demodulation performance is analyzed.The demodulation idea of DSTFT code -free sliding algorithm is given, and its feasibility is proved theoretically.
