ON THE DIMENSIONS OF GOPPA CODES
|
Abstract:
A new lower bound on the dimensions of Goppa codes bas been given by Feng Guiliang (1983). In this paper, at first, a formula for computing the lower bound in some cases is offered, and a upper bound on the dimensions of Goppa codes and a method of finding the upper bound are given. In some special cases, the dimensions of Goppa codes can be obtained by using the upper bound and the lower bound.
