摘要： A radio frequency power amplifier circuit provides linear amplitude modulation of a radio frequency output signal while operating in a saturated amplification mode. The power amplifier circuit incorporates a lossy modulator that functions as a variable resistance responsive to an amplitude modulation signal. A supply voltage is coupled to the voltage supply input of the power amplifier circuit through the lossy modulator, such that the supply voltage applied to the power amplifier varies with the amplitude modulation signal. The radio frequency power amplifier circuit modulates the envelope of an RF output signal generated by saturated mode amplification of a constant envelope radio frequency input signal.

摘要： Techniques for adapting detection schemes used in receivers for receiving radio signals are described. The received signal is processed to determine, for example, an amount of time dispersion present in the radio channel. Based on this determination an appropriate detection scheme is selected for detecting the transmitted symbols. Various techniques for determining the dispersive or non-dispersive nature of the channel are described.

摘要： A system and method for facilitating information interexchange between a wireless telecommunications system having at least one telecommunications device therein and an information service provider. A Business-to-Business (B2B) engine is connected to the telecommunications system for receiving realtime information related to a telecommunications device within the telecommunictions system. This realtime information is provided by the B2B engine to the information service provider, which consequently provides content data to the telecommunications device within the telecommunications system.

摘要： A cellular telephone includes an internally integrated digital entertainment module. The telephone includes a transceiver unit and a headset which is connected to the transceiver unit by wired or wireless link. The entertainment module includes an interchangeable ROM and/or expansion RAM for storing music or other audio signals for playback through the telephone's headset. Music or other audio signals in digitized form is stored in the interchangeable ROM or is loaded into the expansion RAM from a CD player, computer, or other source of digitized audio signals. Under control of the cellular telephone's microprocessor, the digitally stored audio signal is played back through the telephone's headset. The entertainment module may be located in the transceiver unit, a removable battery pack, or in a separate adapter.

摘要： Electronic clock calibration systems, methods, and computer program products use a calibration reference signal to calibrate an electronic clock that generates an output signal and that is responsive to a base reference signal. The base reference signal is less accurate than the calibration reference signal and, therefore, has an actual frequency and an ideal frequency associated therewith. The difference between the actual frequency and the ideal frequency represents the inaccuracy of the base reference signal. The calibration reference signal may be used to determine this difference between the actual frequency and ideal frequency of the base reference signal. Once this difference is determined, the frequency of the electronic clock output signal may be adjusted to compensate for the inaccuracy of the base reference signal. The base reference signal is often generated by a crystal oscillator circuit in consumer electronic devices, which is susceptible to frequency drift based on age, temperature, shock, and other environmental factors. Crystal oscillator circuits have an advantage in that they use relatively little power and, thus, tend to preserve battery life. The accuracy of a crystal oscillator circuit may be improved through use of a more accurate calibration reference signal that need not be available continuously.
