有扰对称信道平均信息量的计算

照相手机让诺基亚抢了风头，这真是亚洲人的失策。在日本和韩国，内置摄像头的手机早就不是什么值得炫耀的东西了。不过日本人的动作还是很快的，GD88和N8一副后来居上的架势，让人不敢小瞧。

How to Calculate the Entropy of Interferential Symmetrical Channels

This paper is mainly concerned with the basic model of infor mation transmission in the interferential symmetrical channels, and from the ang le of the receive end,provides a method calculating the entropy. By making use o f the symmetry, we can find out an easier way to compute the result, keeping awa y from the complicated definitions. A common binary symmetrical channel is showe d as an example.
