Data-aided Symbol Time and Carrier Phase Tracking for Pre-coded Cpm Signals
نویسنده
چکیده
A data-aided 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 and yet simple solution to the tracking problem in the design of coherent CPM receivers.

متن کاملBlind joint estimation of the technical parameters of continuous phase modulated signals
In this paper, a new non data aided estimator of the technical parameters of Continuous Phase Modulated (CPM) signals is proposed. It consists in estimating jointly the modulation index, the symbol period and the frequency offset. It is based on the following observations. Firstly, the inverse of the index is the smallest positive real number a CPM signal should be raised to in order to generat...

Based on a signal representation in a signal space with a few dimensions per interval and data-aided Maximum-Likelihood techniques, new structures for the joint and non-joint estimation of carrier-phase and symbol-timing for general coherent CPM receivers are derived. Due to the choice of proper basis-functions for the signal space, the estimation of symbol-timing becomes a special form of phas...

Abstract |We consider carrier phase and symbol timing synchronization for M-ary partial-response continuous phase modulation (CPM).We focus on developing a classical phase locked loop (PLL)-basedmethod that is robust even forM-ary partial-response CPMs, which has proven to be elusive thus far in the literature. A key part of our design is a simple yet eective timing false lock detector, which ...

Certain problems associated with reliable digital wireless communication over a frequency-flat slow Rayleigh fading channel are treated, when the transmitted signal is modulated using continuous phase modulation (CPM) due to the desirable properties of CPM. The primary focus of attention is on detection strategies, and the thesis proposes iterative detection algorithms for CPM signals transmitt...
