SYSTEM AND METHOD FOR TRANSMITTING AND RECEIVING SIGNAL OF COMMUNICATION MODEM BASED ON FREQUENCY HOPPING

摘要

A system according to an embodiment of the present invention, in a signal transmission/reception system of a communication modem based on frequency hopping, includes a transmission signal processing unit transmitting a signal and a reception signal processing unit receiving the signal, wherein the transmission signal processing unit , a modulator that modulates the signal to be transmitted; Transforms the output signal of the modulator on the frequency axis through a polyphase filter and FFT (fast fourier transform), mixes the order of carriers separated by the polyphase filter and FFT, and changes FFT frequency bin information for each carrier into a time axis signal and signal Multi-channel jump module for processing; and a transmission module for outputting an output signal of the multi-channel hopping module in analog or digital format.
