Abstract
With the quest for software-defined-radio, frequency channelization holds the potential of realizing a system that is as close as possible to Mitola’s architecture. The major premise of Mitola’s architecture is implementing an ADC with a bandwidth wide enough to accomodate the entire RF bands of interest. With current technology, direct implementation of such an ADC is an impossible feat. Nevertheless, proper extension of frequency channelization schemes can potentially achieve an affordable realization of the SDR. This venue of research includes finding the proper bandwidth to strike a balance between the overhead of the extra RF power needed for channelization and the total power consumption of the reduced sampling rate ADCs. Significant research is also required for multiple, simultaneous LO and clock generation schemes for channelization, as well as the potential issues of cross-talk and frequency pulling resulting from implementing multiple LOs on the same chip.
