Fine Carrier Synchronization Unit for a Turbo.

The popularity of the wireless devices comes from several advantages related to this type of communication, i.e. mobility, easy installation and less cost for infrastructure. Hence it is vital to assure a reliable communication where errors can be autonomously fixed and information responsibly secured. The transmission over wireless channel results in frequency and phase offsets; additionally the received symbols are corrupted with noise. Therefore the estimation of the actual frequency and phase offset becomes a very critical task with high impact on communications performance; synchronization is a crucial part of each receiver in digital communication systems. In this context, throughout this work the author proposes an implementation of a Fine Carrier Synchronization Unit that aims a better communication quality and lower its error rate.
