Calculation of Mine Twisted Pair Channel Capacity Based on Water-filling Algorithm

CHENG Ling-fei, MA Xing-he(School of Electrical Engineering & Automation, Henan Polytechnic University, Jiaozuo 454000)  
There are some differences between mine ADSL and common ADSL, the transmission line is the one of the differences.Compared with the common twisted pair, the mine twisted pair has larger diameter, so the pair can carry more data and information.This paper analyzes the characteristics of mine ADSL transmission technology, introduces the procedure for calculating channel capacity of mine twisted pair based on the iterative water-filling algorithm, and on basis of which, the relationship among channel capacity, loop distances and frequency bandwidths of mine twisted pairs.
