众所周知的香农信道容量定义了在带限AWGN信道中通信的最大传输速率。在信号带宽和噪声带宽不同的假设下，证明了一个扩展的信道容量方程。结果表明，在信号带宽和噪声带宽相同的情况下，Shannon信道容量方程只是这种扩展的一个特例，而在不同的信号带宽和噪声带宽情况下，则可以通过这种扩展来计算容量界，这是对信息论的一个重要补充。(C)2009爱思唯尔公司All rights reserved.
The well-known Shannon's channel capacity defines the maximum transmission rate of communications in band-limited AWGN channels. An extended channel capacity equation is proved under the assumption of the different signal and noise bandwidth. Then a special filter named as the geometric feature filter (GFF) and satisfied with this assumption is found. Results indicate that Shannon's channel capacity equation is just a special example of this extension in the case of the same signal and noise bandwidth, but in different signal and noise bandwidth, capacity bounds should be calculated by this extension, which is a very important supplement to information theory.
