Abstract

An accurate band planning algorithm for adjusting the very-high-bit-rate digital subscriber line (VDSL) upstream and downstream band allocation is presented. This algorithm can precisely control the ratio of upstream and downstream transmission rate with accuracy reaching 1% or better. Any ratio of upstream and downstream transmission rates can be obtained with this algorithm. Moreover, transmission capacity can be maximized since larger loading bits will be preferentially selected for the allocation of upstream and downstream transmission. According to complete simulations, the presented band allocation algorithm is analyzed and compared with three commonly used frequency band allocation plans so as to verify the advantages of this algorithm
