Efficient discriminator detection of partial-response continuous phase modulation
Abstract
The aim of this work is to investigate frequency discriminator detection for continuous phase digital modulation (CPM) in order to avoid the RF carrier recovery problem. An efficient demodulation scheme, based on a discriminator followed by a suitable baseband digital processor of acceptable complexity, is presented. The baseband processor is based on decision feedback and correlation. In the binary case a simplified scheme with good performance is also derived.
