Sideband suppression capacity analysis of weighted switch signal

摘要

Any radio transmitting equipment transmits some of the unwanted signal when transmitting the wanted one. Out-band emission is a typical kind of unwanted signal. Aiming at the problem of sideband leakage of PN-code modulating amplitude LFM signal, method of weighting switch signal is proposed. At last, the simulation experiment proved that weighting switch signal with hanning window could suppress sideband effectively.
