关于超宽带无线电基础的介绍以及相关代码，内容详细，通俗易懂，可供大家使用，互相学习。(On the introduction of ultra-wideband radio base and related code, detailed, easy to understand for everyone to use, learn from each other.)

OPNET14.5的帮助文档，几乎所有的现行阶段的教材都是由该软件帮助文档改编或缩减而成，所以该文档为OPNET学习者必备手册之一。(OPNET14.5 the help of documents, almost all of the current phase of the teaching materials are adapted to the software help files or reduced form, so the document must have the manual for one of OPNET learners.)

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.(Computes BER v EbNo curve for convolutional encoding/soft decision Viterbi decoding scheme assuming BPSK.
