通信的数学基础 不错的资料 A Mathematical Theoryof Communication THE recent development of various methods of modulation such as PCM and PPM which exchange bandwidthforsignal-to-noiseratiohasintensifiedtheinterestinageneraltheoryofcommunication. A T 1 2 basis forsuch a theoryiscontainedin the importantpapersof Nyquist and Hartley onthis subject. Inthe presentpaper we will extendthe theoryto includea numberofnewfactors, in particularthe effectofnoise inthechannel,andthesavingspossibleduetothestatisticalstructureoftheoriginalmessageandduetothe natureofthefinaldestinationoftheinformation
