Abstract
A system and method are provided for extracting and demodulating one or more channels in a radio signal. The method includes receiving a first radio signal using a radio frequency front end, translating a first band of frequencies of the first radio signal to a second band of frequencies to generate a second radio signal, digitizing the second radio signal to generate a digital signal, extracting one or more additional band of frequencies of the digital signal, each additional band of frequencies corresponding to a channel, and demodulating one or more channels to generate a respective demodulated signal. In another aspect, a system and method are provided for modulating and combining one or more channels into a radio signal.
