这是通信系统仿真的第六章的例题的仿真程序代码！挺好的，希望对大家有用！(This is a communication system simulation examples of Chapter VI of the simulation program code! Very good, and I hope useful for everyone!)

EEOTS algorithm In this paper We merge two unconnected concepts (i) Channel coding can be used to conserve energy by transmitting at reduced power levels over longer durations. (ii) Electro-chemical mechanisms in batteries allow them to recover energy during idle periods. Two kinds of delay constraints were considered, one a deadline constraint and the other an average delay constraint. We achieve an Energy Efficient transmission compared to an other algorithms.
