Hi ACozma dpu

I am trying to understand demodulation process in this tutorial: http://www.analog.com/en/analog-dialogue/articles/using-model-based-design-sdr-2.html 

I have problems with understanding some computations. For example:

- in Detector block in stateflow chart, variable T0Delay is used to wait for 25 samples in case SyncCorr will increase above maxSync? Am I right? what is the purpose of this variable?

- in Detector block in Bit Process block, what is the purpose of the HDL Counter and comparing it inputs ? 

- and where is algortihm which is comparing detected preable with pre-definied preable?

I will be very greatful if somebody will clarified be those things.

Thanks in advance

Martin
