- sdr.plot.ber(ebn0: ArrayLike, ber: ArrayLike, **kwargs)
Plots the bit error rate (BER) as a function of \(E_b/N_0\).
- Parameters:¶
- ebn0: ArrayLike¶
The bit energy \(E_b\) to noise PSD \(N_0\) ratio (dB).
- ber: ArrayLike¶
The bit error rate \(P_b\).
- **kwargs
Additional keyword arguments to pass to
matplotlib.pyplot.semilogy()
.
Examples¶
Plot theoretical BER curves for BPSK, QPSK, and 8-PSK in an AWGN channel.
