Abstract

The issues of suppressing chirp interference in traditional wireless communication systems are studied in this paper. The principle of chirp interference is explained from a new perspective. The band-stop filtering (BSF) in the fractional Fourier transform (FRFT) domain is proposed, which is more effective than common methods such as band-pass filtering (BPF) in the frequency domain, verified by theoretical analysis and simulation results.

Keywords: ﬁltering chirp modulation constellation fractional fourier transform
