A kind of realizable digital baseband part-response system
Deng Xiang-yu · Information technology newsletter · 2005
In process of baseband transmission for digital signal, the part-response system based on ideal system of non-intersymbol interference is often used in order to get the system transmission function that is of not only high frequency utilization-rate but also quick high-frequency attenuation. However, as ideal system it is not procurable in fact, that means is of disfigurement. This text begins with rise-cosine system, combining the elementary principle of avoiding intersymbol interference and according to the means of ideal part-response system, the error-transmission and the credibility-transmission for the realizable part-(response) system are discussed in theory, accordingly a kind of theory is given for the practical application.
