Seeing as how this question was never answered, I may have to go directly to NI support for this follow up question, but does anyone know what frequency, phase, and timing recovery loops are implemented in the receiver in the MT Demodulate QAM block? It's hard to tell from reading the LabVIEW code. I'm looking for some documentation that says "Costas Loop" etc.
