A general method for passband quantization noise suppression in pulsed transmitter architectures.
Artikel i vetenskaplig tidskrift, 2009

In this paper we describe a novel method for selective bandpass cancellation of the quantization-noise that occurs in pulsed transmitter architectures, where the signal is partially or completely quantized. A carrier bursting transmitter architecture, where the amplitude part is quantized and then recombined with a phase-modulated RF carrier, is used as a general example to demonstrate the principles of the method proposed. Measurements on a high efficiency 10 W LDMOS PA working at 1 GHz are used to verify the theoretical results.
