optic.comm.metrics.fastBERcalc

fastBERcalc(rx, tx, M, constType, px=None)

Monte Carlo BER/SER/SNR calculation.

Parameters:

• rx (np.array) – Received symbol sequence.

• tx (np.array) – Transmitted symbol sequence.

• M (int) – Modulation order.

• constType (string) – Modulation type: ‘qam’, ‘psk’, ‘pam’ or ‘ook’.

• px ((M, 1) np.array) – Prior symbol probabilities.

Returns:

• BER (np.array) – Bit-error-rate.

• SER (np.array) – Symbol-error-rate.

• SNR (np.array) – Estimated SNR from the received constellation.
