Implementation of synchronization algorithms, carrier phase recovery and symbol timing recovery, on a digital signal processor
Mustapha Benssalah, Mustapha Djeddou · 2009
In this paper, an implementation of synchronization algorithms in digital communication systems such as carrier phase recovery and symbol timing recovery is presented. For this implementation, we use the development kit TMS320C6711 DSK with a rapid prototype method. The implemented algorithms are founded on estimators and detectors derived from the maximum likelihood (ML) approach. Feedback and feedforward structures are considered. These algorithms operate in non-data-aided (NDA) mode or decision directed (DD) mode. For the problem of symbol timing recovery synchronization, we used the Gardner, Early Late Gate and Mueller & Muller algorithms. The obtained implementation results are very promising.
