统计/判决电路在通信电子实验教学中的应用

鉴于通信电子技术课程的教学现状,提出了依据统计/判决电路来设计通信电子实验,在8分频的前提下,该电路可以在改进系统通信质量方面起到一定的作用,如改善信噪比,降低误码率,提高系统抗干扰性。通过对该电路的设计、制作和调试,学生能掌握诸如香农公式、数字信号最佳接收等理论知识。能较好实现培养理论和实际动手能力相结合的教学要求。

Application of the Statistic/Judgement Circuit in Experimental Teaching of Communication Electronics Technology

In view of the present teaching status of Communication Electronics Technology course,this paper introduced how to design experiments according to the statistic/judgement circuit.Under the pre-condition of eight frequency divisions,this circuit can be used to improve the communication quality of the system,such as improving the signal/noise ratio,reducing the miscarriage code rate,advancing the characteristics of anti-jamming.By designing,manufacturing and debugging the circuit,students can learn a great deal on subjects such as Shanon Formulas and the optimal digital signals receiving,and also achieve the teaching requirement of cultivating the ability of applying theory into practice.
