摘要
为了帮助学生更好的理解香农信道容量的定义,激发学生学习信息论课程的兴趣,设计了香农"免费午餐"理论的实验课。以二进制对称信道上重复码内容开始,通过设计数值实验,得到了误码率-传输速率的关系,进而揭示了香农惊人的"免费午餐"理论的内涵,理论联系实际,教学效果显著。
To help students better understand the essence of Shannnon channel capacity and a-rouse their learning interests, the experiment course related to Shannon＇s“free lunch” theory is devised. The teaching process is started from the content of replication code for binary symmetric channel. By designing numerical experiment, the relationship between error bit rate and trans-mission rate is obtained, from which the amazing theory of Shannon＇s“free lunch” theory is fully revealed. Better teaching results are obtained by linking theory with practice.
