  • COMMUNICATION DEVICE, SPREAD-SPECTRUM RECEIVER, AND RELATED METHOD USING NORMALIZED MATCHED FILTER FOR IMPROVING SIGNAL-TO-NOISE RATIO IN HARSH ENVIRONMENTS
    Publication number: 20200091960
    Abstract: A communication device, a method of operating a communication device, and a spread-spectrum receiver are disclosed. The method includes receiving an incoming RF signal, demodulating the incoming RF signal to generate a baseband signal, filtering the baseband signal with a normalized matched filter having filter characteristics matched to a pulse-shaping filter of the transmitter that generated the incoming RF signal, and extracting a received signal from a normalized output generated by the normalized matched filter. As a result, interferences and noise from harsh environments may be suppressed.
