Method and system for channelization and down conversion of wideband subscriber information signals

The invention describes a method and system for channelization through the application of a weighted chirp pulse. The impulse response of a desired filter weighting is applied to the output of a chirp pulse generator (FIG. 1, 150). The resulting weighted chirp pulse is then applied to the a first columnar Bragg cell (80) while an unweighted chirp pulse is applied to a second columnar Bragg cell (90). A modulated energy beam (55) is then allowed to pass through both Bragg cells. The resultant spatially dispersed energy beam (95) is then applied to lens (120) and projected onto a detector array (130). The detector array (130) then extracts the subscriber transmitted information from the projected interference pattern.
