The Receiver: Analog RF Front-End,ted at baseband, in the digital domain. Use of such techniques as sampling demodulation and homodyne receiver architectures all present new methods in developing high-performance demodulators, which take advantage of the fact that digital data – spread-spectrum digital data – is being transmitted.

Broadband RF Transmission and Modulation,le-sideband frequency upconversion. Single sideband is necessary since the first stage of up-conversion has been performed in the digital domain — the output of the modulator is centered at 64 MHz, not DC.
