Efficient Discriminator Detection of Partial-Response Continuous Phase Modulation
S. Bellini, Guido Tartara · IRE Transactions on Communications Systems · 1985
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 processoris based on decision feedback and correlation. In the binary case we also derive a simplified scheme with good performance.
