Measurement code for the probability of successful delivery (PSuD)

PURPOSE

The purpose of this software is to measure the Probability of Successful Delivery (PSuD) of a push-to-talk network. PSuD generally describes the likelihood that a message of a given length.

Currently there is no published paper on PSuD, check back with [e-mail] for more information.
