Detailed Description

DASK Demodulator with quasi coherent differential demodulation (i.e. requires ambigous channel information) MetricQC() determines the way of metric calculation. Since this function is virtual it can be overridden by a derived class. The standard implementation of MetricQC() in this class does not consider the distance between the received complex value and the values of the used ASK-constellation diagramm, but it considers the difference between the absolute values of both.

Member Function Documentation

virtual void simthlib::DaskDemodulatorQC::MakeMetric (  Complex  sym, Complex  prev_sym, simth::Llv *  llv )  const [protected, virtual]

Returns the metric for the given symbol sym by the symbol itself and the reference symbol prev_sym. If a derived class needs channel information to calculate the metric, the function of the derived class should throw an error. Implements simthlib::DiffDemodulatorMetric.

virtual void simthlib::DaskDemodulatorQC::MakeMetric (  Complex  sym, Complex  prev_sym, simth::Llv *  llv, Complex  h2, Complex  h1, double  noise )  const [protected, virtual]

Returns the metric for the given symbol sym by the symbol itself, the reference symbol prev_sym and the channel information h2, h1, noise. However, a derived class does not need to use the channel information (e.g. standard incoherent differential demodulation). Implements simthlib::DiffDemodulatorMetric.

virtual void simthlib::DaskDemodulatorQC::MetricQC (  Complex  sym, Complex  prev_sym, simth::Llv *  llv, Complex  sc2, Complex  sc1, double  noise )  const [protected, virtual]

virtual void simthlib::DaskDemodulatorQC::print (  std::ostream &  os  )  const [virtual]

Reimplemented from simthlib::DaskDemodulator.
