Publication number: 20140254722Abstract: A receiver and method is provided for sigma-delta converting an RF signal to a digital signal and downconverting to a digital baseband signal. The RF signal is split into N phases, as can be accomplished using a sample and hold circuit, and each phase is digitized, as can be accomplished using an analog-to-digital (A/D) sigma-delta converter.

Patent number: 8553807Abstract: Methods and apparatus are described herein that make use of complex tuning, the inherently repetitive nature of sampled signals, and programmable digital filtering to create a flexible digital up-conversion system that utilizes a digital-to-analog converter (DAC) with a fixed effective sample rate while still being adapted for tunability over a wide frequency range. With a knowledge of the fixed effective sample rate of the DAC and a desired frequency of up-conversion and combining complex tuning at baseband and up-sampling by a factor of N with a programmable passband filter configured to select one of a plurality of signal images resulting from the up-sampling, it is possible to translate a baseband input signal to a wide range of frequencies above or below Fs, without changing the sampling rate of the fixed rate DAC used in the up-conversion process.Type: GrantFiled: October 20, 2008Date of Patent: October 8, 2013Assignee: Apple Inc.Inventors: Bradley John Morris, Arthur Thomas Gerald Fuller

Patent number: 8406348Abstract: Systems and methods are disclosed that include selecting a sampling frequency and a tuning resolution frequency. These systems and methods may further include determining a wordlength of the phase accumulator, a numeric representation of the phase range, and a reduced representable value of a phase accumulator.

Patent number: 8391809Abstract: In an embodiment, a system for multi-band predistortion has a predistortion actuator applying a first and a further adjustable distortion to a first band input and at least one further band input, respectively, based on the first band input and at the least one further band input to provide a first band output and a second band output, respectively. The predistortion actuator drives an output port configured to be coupled to an amplifier. The system further has a processor coupled to an evaluation input, which is couplable to an output of the amplifier. A coefficient calculation block is coupled to a processor output, the first band input, and the at least one further band input. The coefficient calculation block calculates first and the further adjustable distortion coefficients based on the first band input, the at least one further band input and the processor output.Type: GrantFiled: October 13, 2011Date of Patent: March 5, 2013Assignee: FutureWei Technologies, Inc.Inventor: Arthur Thomas Gerald Fuller

Patent number: 8369447Abstract: A predistortion actuator is provided. The predistortion actuator includes a plurality of branches, each of which implements a basis function that acts on a digital input signal. For at least one of the branches, the respective basis function is a sectioned basis function, where each section of the sectioned basis function corresponds to a respective section of a range of at least one input signal characteristic associated with the digital input signal, such as a value range of a magnitude, a temporal characteristic, or a hybrid of the two. A power amplifier system including the predistortion actuator is also provided. Utilizing sectioned basis functions can potentially reduce the hardware resources necessary to realize the predistortion actuator relative to conventional global basis functions. In addition, signal conditioning during coefficient training can potentially be used to reduce the dynamic range of coefficients associated with each sectioned basis function.Type: GrantFiled: March 12, 2009Date of Patent: February 5, 2013Assignee: Apple Inc.Inventors: Arthur Thomas Gerald Fuller, Bradley John Morris
