# this script characterizes a single code over a narrow range of Eb/No
# note relationship between noise standard deviation, sigma, and Eb/No:
# Ps/Pn = 1/(2*sigma^2)
# Ps/Pn = (Es/tau_s)/(W*No)=(Eb/R)/(tau_s*W*No)=(Eb/No)*(1/(tau_s*R*W))
# If pulses are sent at Nyquist signaling limit, then: 1/tau_s=2*W -> tau_s*W=1/2
# so Eb/No=(1/2*sigma^2)*(2*R) =
# Eb/No = 1/(2*R*sigma^2)
# If R=1/2, then Eb/No = 1/sigma^2 Right? Check this.
