Computes BER v EbNo curve for convolutional encoding / soft decision

Viterbi decoding scheme assuming BPSK.

Brute force Monte Carlo approach is unsatisfactory (takes too long)

to find the BER curve.

The computation uses a quasi-analytic (QA) technique that relies on the

estimation (approximate one) of the information-bits Weight Enumerating

Function (WEF) using

A simulation of the convolutional encoder. Once the WEF is estimated, the analytic formula for the BER is used.
