Broadband Signal Spectrum Monitoring Method Based on Chirp-Z Transform
Yalan Song, Zhibin Zeng · 2015
Sampling rate reduction is a key to spectrum analysis of broadband signals.To avoid spectrum aliasing, the sampling rate for broadband signal is always too high for implementation.In this paper，a new spectrum analyzing method based on respectively signal is proposed.Compared with conventional FFT, the Chirp-Z transform has the advantages of low sampling rate and high -resolution.Simulation results show that the Chirp-Z transform can achieve better spectrum analysis performance with the significant reduction on sampling rate.
