Abstract
The present invention is addressed to a method of modulation wherein digital data streams are radio transmitted at a high level of efficiency and speed, and without a large continuous concomitant formation of side frequency phenomena. Thus, bandwidths assigned for this transmissional task are quite narrow, with data transmission speeds at the singular frequency of the RF carrier itself. This invention can send high-speed data in RF channels that are very narrow and that would ordinarily be considered useful only for very low speed data or analog voice. The purpose of this invention is to provide a means by which a radio frequency carrier, expressed, as a square wave can be amplitude modulated with maximum efficiency and speed with minimum phase delay and distortion. RF filtering is used to reduce the modulated square wave to its base band sine wave component after modulation. This circuit may be used to modulate the carrier (clock) at any frequency up to and beyond the carrier frequency itself. This is useful in the implementation of broadband wireless systems. This invention can also be used with multiple access systems.
