Est_BER_vs_EbN0.png (576 × 438 pixels, file size: 22 KB, MIME type: image/png)

estimated BER vs. Eb/N0 in dB

Calculated using formulas: bpsk, qpsk: 0.5erfc(sqrt(Eb/N0)) (M)psk: 1/m erfc(sqrt(m*(Eb/N0) * sin(pi()/pow(2,m))) with M = pow(2,m) (M)QAM: 2/m(1 - (1/sqrt(pow2,m)) * erfc(sqrt( 1.5 * Eb/N0 * m/(pow(2,m)-1))) DBPSK: 0.5e^Eb/N0

erfc: complementary error function

*NOTE:* formulas given in [1]
