A radio signal transmission technique includes selecting a sample rate from a plurality of predefined sample rates so that the radio signal is contained entirely within a Nyquist zone corresponding to the sample rate. A digitized signal is converted to an analog signal, spectrally enhanced, and passed through a selected one of a plurality of selectable bandpass filters to form the radio signal.

Multi-band direct sampling transmitter

A radio signal reception technique includes selecting a sample rate from a plurality of predefined sample rates so that the radio signal is contained entirely within a Nyquist zone corresponding to the sample rate. The radio signal is passed through a selected one of a plurality of selectable bandpass filters to provide an analog signal. The analog signal is sampled at the sample rate and converted to a digital signal.
