论带通信道的信道容量的不确定性

依据山农的经典论证方法 ,证明山农信道容量定理仅适用于低通信道 ,不适用于带通信道。对于带通信道 ,信道容量将随信道通带的中心频率而改变。所以带通信道的信道容量具有不确定性。

On an Indeterminacy of the Channel Capacity for Band-pass Channel

It is proved in this paper on the basis of the classical methods of C.E.Shannon that Shannon channel capacity theorem is only applicable to the lowpass channel,but not to the band pass channel.For the band pass channel the channel capacity changes with the centre freguence of the pass band.Therefore,the channel capacity of band pass channel is passessed of an indeterminacy.
