摘要： A low cost high-efficiency all-digital transmitter using all-digital power amplifiers (“DPA”) and various mapping techniques to generate an output signal, which substantially reproduces a baseband signal at a carrier frequency. A baseband signal generator generates a baseband signal which is quantized by a signal processor using a quantization map. A DPA control mapper outputs control signals to phase selectors using the quantized signal and a quantization table. Each phase selector receives one of the control signals and outputs a waveform at a carrier frequency with a phase corresponding to the control signals, or an inactive signal. Each DPA in a DPA array has an assigned weight, receives one of the waveforms from the phase selectors, and outputs a power signal according to the weight of the DPA and the phase of the received waveform. The combined power signal substantially reproduces the baseband signal at the carrier frequency.

摘要： Methods and apparatus for conditioning communications signals based on detection of high-frequency in the polar domain. High-frequency events detected in a phase-difference component of a complex baseband signal in the polar domain are detected and used as a basis for performing hole-blowing on the complex baseband signal in the quadrature domain and/or nonlinear filtering either or both the magnitude and phase-difference components in the polar domain. Alternatively, high-frequency events detected in the phase-difference signal that correlate in time with low-magnitude events detected in a magnitude component of the complex baseband signal are used as a basis for performing hole-blowing on the complex baseband signal in the quadrature domain and/or nonlinear filtering either or both the magnitude and phase-difference components in the polar domain.

摘要： The present invention relates to a method and system for glitch correction in an all digital phase lock loop. An all digital phase lock loop can include a phase error signal generation unit, a multi-phase oscillator, a glitch correction unit, and a phase to digital converter. The phase to digital converter receives a multi-phase signal from the multi-phase oscillator and generates a phase signal. The error signal generation unit receives the phase signal and a reference phase signal and generates a phase error signal, which is fed to the glitch correction unit. The glitch correction unit removes the glitches in the phase error signal by a portion of the phase error signal. The phase lock loop can also include a phase rotator and a calibration block. The calibration block instructs the phase rotator to rotate the multi-phase signal by the phase rotation which generates the minimum number of glitches.
