ABSTRACT:
A flexible-bandwith radio is provided. Briefly, the radio is equipped with a multiplicity of modulator and demodulator units arranged to communicate on a multiplicity of discrete frequency bands. There is no need for the individual frequency bands to be contiguous. As a result, the radio is able to simultaneously supporting a multiplicity of band-limited radio channels. The radio is further equipped with a channel combiner unit and a channel divider unit to combine the individual channels to form a high-capacity aggregate channel. The aggregate channel is then provided to the user, or to a user application. In a first embodiment, the radio utilizes a multiplicity of discrete modulator, demodulator, combiner, and divider units. In a second embodiment, the radio utilizes a suitably-programmed digital signal processor to perform the equivalent modulator, demodulator, combiner, and divider functions.
