%description
Provides maximum likelihood estimates of the performance parameters that
drive a binomial distribution of observed errors, and takes full advantage
of zero error observations. High performance communications systems
typically have inherent noise sources and other performance limitations
that need to be estimated. Measurements made at high signal to noise
ratios typically result in zero errors due to limitation in available
measurement time. Package includes theoretical performance functions for
common modulation schemes (Proakis, "Digital Communications" (1995,
<ISBN:0-07-051726-6>)), polarization shifted QPSK (Agrell & Karlsson
(2009, <DOI:10.1109/JLT.2009.2029064>)), and utility functions to work
with the performance functions.
