摘要
PURPOSE: A performance analyzing method for a CSS(Chirp Spread Spectrum) system corresponding to a tone jamming signal is provided to analyze the signal model of a CSS communication system in a tone jamming environment, thereby providing a SER analytical method. CONSTITUTION: A transmitter of a CSS(Chirp Spread Spectrum) system models a transmission signal. A received signal is modeled with the modeled transmission signal through multiple jamming signals. The modeled received signal models an output signal which has gone through a down-chirp filter in a signal space. The CSS system induces a closed shape SER(Symbol Error Rate) expression. The process which models the transmission signal is comprised as follows. The phase is falsified to a short pulse of IF at each symbol period.
