Abstract: An integrated circuit device has a modulator module that provides a modulation signal comprising one frequency keyed on and off, or alternating between two or more different frequencies or phases that are selected based upon a modulator signal. The one or more frequencies or phases may be selected from a plurality of frequency sources. Switching the one frequency on or off, or between the at least two different frequencies or phases may be synchronized with one or both of the two or more different frequencies or phases so that "glitches" or spurs are not introduced into the modulation signal. The integrated circuit device may also comprise a processor, memory, digital logic and input-output. Frequency sources may be internal to the digital device or external. The modulator signal may comprise serial data generated from the digital logic and/or processor of the digital device.

Abstract: An alternative approach to coping with the ever increasing demand for faster communications hardware is to design modems that are capable of operating its speeds at a higher data rate than a speed required for a single port of the standard communication rate for that modem. Basically, by utilizing a resource manager, that directs the data in and out of the various portions of the modem in an orderly manner, keeping track of which of the ports is being operated at any given point in time, a standard single port modem can be reconfigured, for example, at an over clocked rate, to manipulate the data input and output of a modem.

Abstract: A low-power digital frequency synthesizer combining direct digital frequency synthesis techniques with serrodyne frequency translation principles to produce a wideband frequency response with high spectral purity. A conventional direct digital synthesizer is used to generate a high-resolution analog carrier signal from a low-speed digital clock signal. The carrier signal is phase modulated by a low-resolution signal generated from a high-speed digital clock signal. The modularity signal is a higher frequency signal than the carrier signal. The phase modulation is accomplished by exact decoded gain elements. The spectral purity of the resulting high-resolution output signal is unobtainable by conventional direct digital synthesizers, while providing significant power savings.

Abstract: Interference is processed in a waveform received at a device in a wireless network, the received interference comprising non-linear products of at least a first signal (C 1 ) at a first carier frequency and a second signal (C 2) at a second carrier frequency. A complex composite baseband signal is generated comprising at least the first and second signal at baseband, occupying a respective first and second frequency range within a composite baseband frequency range and not overlapping in frequency, by frequency shifting at least one of the first and second signals within the composite baseband frequency range. The complex composite baseband signal is processed by applying at least a first non-linear function (74a) to generate simulated interference comprising at least one simulated non-linear product. The received interference is then processed in dependence on the simulated interference.

Abstract: The invention disclosed in this application uses a method of modulation named Integer Cycle Frequency Hopping (ICFH) wherein a carrier signal, comprised of a continuum of sine waves is generated on a single frequency. A data bit representing either a “1” or a “0”, depending upon the logic polarity chosen by the builder is imposed upon the carrier signal by modifying the carrier signal at precisely the zero crossing point or the zero degree angle. The method of imposing the data is to cause either a lengthening or shortening of the proceeding 360 degrees of phase angle, thus effectively either raising or lowering the frequency of the carrier signal for just the one, or a succession of cycles at hand. Upon completion of the 360-degree cycle(s), the carrier will return to the original frequency. The main carrier frequency is only modulated beginning at the zero degree phase angle and ending at the 360-degree phase angle. In this modulation scheme as few as one sine wave cycle can be used to represent one data bit. The spectral output of a transmitting device using this modulation scheme will be defined by the difference in frequency between the main carrier signal and the modulating frequency. In the resulting signal a modulated segment of the main carrier frequency can represent either a binary “1” or a binary “0”.
