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

Reimplemented from inet::physicallayer::MqamModulationBase.

     double ber = calculateSER(snir, bandwidth, bitrate);
     ASSERT(0.0 <= ber && ber <= 1.0);
     return ber;
 }

◆ calculateSER()

double inet::physicallayer::QbpskModulation::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.

Reimplemented from inet::physicallayer::MqamModulationBase.

 {
     double ser = 0.5 * erfc(sqrt(snir * bandwidth.get() / bitrate.get()));
     ASSERT(0.0 <= ser && ser <= 1.0);
