Data-Aided Symbol Time and Carrier Phase tracking For PRE-Coded CPM Signals

摘要

A data-adied approach to symbol time and carrier phase synchronization applicable to general continuous phase modulation (CPM) signals with modulation index 0.5 is described. Simulated BER performance of two receivers equipped with these synchronizers is presented for a GMSK BT=1/5 signal received in noise with constant and dynamic synchronization errors. Results demonstrate that these synchronizers provide a very promising nad yet simple solution to the tracking problem in the design of coherent CPM receivers.
