    Abstract: A technique of processing an input signal having an input signal phase is disclosed. The technique includes determining a number of transitions of the input signal within a period having a start and an end. The technique includes determining a relative beginning phase of the input signal at the start of the period, which includes generating a first reference signal having a first reference signal frequency and a first reference signal phase synchronized with the start of the period, and detecting a first time interval required for the input signal phase to have a first specified relationship to the first reference signal phase. The technique includes similarly determining a relative ending phase of the input signal at the end of the period. The technique includes determining an input signal temporal characteristic from the number of transitions and the relative beginning phase and the relative ending phase.

    Abstract: The present invention includes systems and methods for altering a cellular phone user's speech so that the speech can be less bothersome to third parties in the surrounding area and so that the user has more privacy. Sound cancellation can be used to cancel, reduce, or modify the user's voice so third parties cannot hear the voice as easily or so that the user's voice cannot be understood. Furthermore, the user device can encourage the user to speak in a lower voice. The user device can accomplish this encouragement by indicating to the user their level of speech. In this manner, the user knows when he may lower his voice and yet still provide an adequate volume of speech for the cellular phone. Additionally, the user device can encourage the user to speak in a lower voice by audibly playing back the user's voice in real time.

    Abstract: Methods and apparatus for reducing signal degradation of a communications signal caused by reducing the average-to-minimum amplitude ratio (AMR) of a communications signal. According to one exemplary method, times when the amplitude of a communications signal falls below or is likely to fall below a predetermined magnitude minimum. Corrective pulses are generated, which are combined with the communications signal in the temporal vicinities when the amplitude of the communications signal falls below the predetermined magnitude minimum, to reduce the AMR of the communications signal. The corrective pulses are generated by a nonlinear filter that is configured to minimize the amount of in-channel distortion the corrective pulses introduce to the communications signal by their insertion while substantially preserving an out-of-band measure of quality of the communications signal.

    Abstract: This invention, generally speaking, modifies pulse amplitude modulated signals to reduce the ratio of average power to minimum power. The signal is modified in such a manner that the signal quality remains acceptable. The signal quality is described in terms of the Power Spectral Density (PSD) and the Error Vector Magnitude (EVM).
