摘要： A technique that reduces or eliminates trading-off power amplifier efficiency and costly external filtering in amplitude and phase modulated sinusoidal signal generation uses multi-phase outphasing and a multi-phase switching mode power amplifier to generate the amplitude and phase modulated sinusoidal signals. The technique combines multiple clock phases with sinusoidally weighted circuits of the switching mode power amplifier to improve amplitude and phase modulated sinusoidal signal generation.

摘要： Methods and apparatus are provided for modeling of a physical system using two-dimensional look-up tables. A method can include determining coefficients for a piece-wise polynomial function that estimates a non-linear function, storing the coefficients as entries in one or more two-dimensional look up tables in the memory, receiving a complex value input corresponding to an actual input value, identifying two closest entries, a first closest entry and a second closest entry, to the complex input value in a two-dimensional look-up table of the one or more two-dimensional look-up tables, evaluating, using the one or more hardware processors, the piece-wise polynomial function at the complex input value twice, a first evaluation using the coefficients corresponding to the first closest entry and a second evaluation using the coefficients corresponding to the second closest entry, to generate first and second output values, and generating an output value by performing a linear interpolation between the first and second output values.

摘要： Methods and systems are described for calibrating phase hardware-induced distortion in a cellular communications system. In one aspect, an estimate of a phase difference at a user equipment (UE) between downlink channels including signals sent over two or more BS transmitter chains is obtained. A phase difference between uplink channels including signals received over two or more BS receiver chains is determined. A relative phase distortion induced by two or more BS transceiver chains is determined based on the received estimate of phase difference between downlink channels and the determined phase difference between uplink channels.

摘要： A radio frequency (RF) transmitter has at least one digital signal processing module and at least one power amplifier module. The digital signal processing module includes at least one digital pre-distortion component arranged to receive at least one complex input signal, perform two-dimensional non-uniform mapping of the complex input signal to a first, in-phase, digital pre-distortion control word and a further, quadrature, digital pre-distortion control word, and output the in-phase and quadrature pre-distortion digital control words. The power amplifier module includes a first, in-phase, array of switch-mode power cells and at least one further, quadrature, array of switch-mode power cells. The two-dimensional non-uniform mapping has a pre-distortion profile at least partly based on an input/output relationship for the power amplifier module arranged to generate an analog RF signal based at least partly on the in-phase and quadrature digital pre-distortion control words.
