摘要： A multi-carrier transmitter and methods thereof are provided. For example, a multi-carrier transmitter comprises a processor operable to receive a plurality of baseband signals. Each of the plurality of baseband signals correspond to a separate data communication. A modulator is in communication with the processor. A non-linear device is in communication with the modulator. The processor is further operable to combine the plurality of baseband signals to generate a composite baseband signal. The modulator is operable to modulate a carrier signal with the composite baseband signal to generate a multi-carrier signal. The multi-carrier signal is provided to an input of the non-linear device.

摘要： A method and apparatus for a multi-mode and multi-rate telemetry transmitter includes a digital baseband lineup, a digital-to-analog converter (“DAC”), and an analog reconstruction filter. The digital baseband lineup may be programmed to any desired bit rate, enabling the transmitter to support multi-rate capabilities. Different coefficients and numerical values may be programmed in the digital baseband lineup to support any desired modulation scheme, enabling the transmitter to support multi-mode capabilities. The digital baseband lineup may be designed by implementing up-sampling stages, down-sampling stages, and digital filters in a variety of arrangements.

摘要： A digital polar transmitter includes a baseband processor configured to receive an input signal and to convert the input signal into a baseband amplitude component and a baseband phase component. The transmitter also includes a phase modulator in communication with the baseband processor. The phase modulator is configured to modulate an RF carrier signal based on the phase component and to generate a phase-modulated RF carrier signal. A power amplifier is provided in communication with the baseband processor and the phase modulator. The power amplifier is configured to amplify the phase-modulated RF carrier signal based on the baseband amplitude component and to generate an amplified RF signal. The transmitter also includes a digital feedback loop in communication with the power amplifier and the baseband processor. The digital feedback loop is configured to detect the amplified RF signal and to provide a digital amplitude feedback signal and a detected phase feedback signal to the baseband processor.

摘要： A target receives two signals of different modes in association with a first location and another two signals in association with a second location. The first two signals are assumed to have been emitted effectively simultaneously from the first location, and the second two signals are assumed to have been emitted effectively simultaneously from the second location. A first distance is calculated in view of a receipt time difference of the first two signals in view of differing rates of propagation assumed between these two signals; a second distance is calculated in view of another receipt time difference of these second two signals in view of differing rates of propagation assumed between each of these other signals. A possible location of the target is then calculated in view of the first distance and its associated first location and the second distance and its associated second location.
