     return erfc(sqrt(snir) * sin(M_PI / constellationSize)) / codeWordSize;
 }

double inet::physicallayer::MPSKModulation::calculateSER	(	double	snir,
		Hz	bandwidth,
		bps	bitrate
	)		const

overridevirtual

Returns the symbol error rate as a function of the signal to noise and interference ratio, the bandwidth, and the gross (physical) bitrate.

Implements inet::physicallayer::IModulation.

 {
     // http://www.dsplog.com/2008/03/18/symbol-error-rate-for-16psk/

	)		const

overridevirtual

Prints this object to the provided output stream.

Function calls to operator<< with pointers or references either const or not are all forwarded to this function.

Reimplemented from inet::physicallayer::APSKModulationBase.
