3 energy per bit (Eb) /spectral noise density (No).
отношение битовой энергии к плотности спектрального шума
Определяет коэффициент сигнал/шум в цифровых коммуникационных системах и служит основным показателем качества сигнала. Различные формы модуляции (BPSK, QPSK, QAM) имеют разные теоретические функции зависимости уровня битовых ошибок BER от Eb/No. Пользуясь этими функциями можно рассчитать пропускную способность линии связи при заданном уровне BER. Также значение Eb/No позволяет вычислить отношение мощности сигнала к мощности шума на входе приемника C/N - carrier-to-noise или CNR - carrier-to-noise ratio.
