Abstract: A method for determining a noise shaped quantized parameter contributing to generation of an output signal comprises estimating an error within the output signal using a quantization of the parameter and a quantization of a further parameter contributing to generation of the output signal. The quantization of the parameter is used as the noise shaped quantized parameter according to a selection criterion.

Abstract: An apparatus for generating a radio frequency signal is provided. The apparatus includes a modulator configured to generate the radio frequency signal based on an input signal. Further, the apparatus includes a controller configured to control the modulator to generate the radio frequency signal using polar modulation, if the input signal has a first characteristic. The controller is configured to control the modulator to generate the radio frequency signal using quadrature modulation, if the input signal has a different second characteristic.

Abstract: A method for approximating a first signal having a first oscillation period within a quantized time interval using a second signal is provided. The second signal has a second oscillation period. The method includes calculating a phase offset of the first signal at at least one position within the quantized time interval. Further, the method comprises shifting the second signal within the quantized time interval until a phase offset of the second signal at the at least one position satisfies a quality criterion related to the phase offset of the first signal.

Abstract: An apparatus and a method for transmitting a signal over a wireless channel using a device including a polar transmitter joinable with a modulator are disclosed. For example, the method, by a circuit of the device, generates first and second streams of data from received data based on a type of modulator, a type of combiner and a channel frequency, each stream having at least some portion of the received data that is distinct from data included in the other stream, the type of combiner comprising a multiplicative or an additive combiner, the method, by the circuit, generates a first analog signal based on the first stream and generates a supply voltage based on the second stream, and the method by an amplifier coupled to the circuit, generates a Radio Frequency (RF) signal based on the supply voltage and the type of combiner.
