1. A communication system for millimeter-wave wide-bandwidth bands comprising (a) a transmitter having a source and comprising: (i) a voltage-controlled oscillator arranged to generate an output signal having a oscillation frequency, (ii) said voltage-controlled oscillator having at least one control-signal input, said voltage-controlled oscillator being arranged to control said oscillation frequency of said output signal in response to a control-signal supplied to said control-signal input, (iii) a circuit means arranged to generate said control-signal, (iv) a multiple-state system that can assume a plurality of states and change its state based upon said oscillation frequency, (v) a first means for causing said multiple-state system to assume a unique one of said plurality of states in a preset time interval, and (vi) a second means for comparing said unique state to a predetermined desired state after it is set to said unique state in said preset time interval and thereby modify said control-signal, (vii) a third means for creating a modulated signal for transmitting information utilizing said output signal of said voltage-controlled oscillator, (b) a receiver for receiving said modulated signal, and (c) a fourth means in said receiver containing for demodulating said modulated signal in a non-coherent manner, whereby said communication system transmits and recovers said information, and said communication system for said millimeter-wave wide-bandwidth bands has reduced power requirements, complexity, and spurious signals.
