* \brief High optimized vector correlator class
* \brief Class that implements carrier wipe-off and correlators.

* Implemented versions:
* - Generic: Standard C++ implementation.
* - Volk: uses VOLK (Vector-Optimized Library of Kernels) and uses the processor's SIMD instruction sets. See http://gnuradio.org/redmine/projects/gnuradio/wiki/Volk
