A Brief Analysis of the Relationship between System Bandwidth and Code Speed in the Digital Baseband System
Xiangyu Deng · Journal of Lanzhou Polytechnic College · 2003
Both system bandwidth and transmission speed of code are very important property parameters in the baseband transmission process for digital signals. Transmission speed of code not only accords with Shannon expressions but also is limited by intersymbol interference.It is necessary to make determinate relationship between system bandwidth and transmission speed of code to avoid intersymbol interference.By analysing several normal systems according to the method of unit-impulse response being zero,their scaling relationship has been explained in this paper,which gives a theoretical guidance for the practical application.
