有限网格上Downset码的译码
Decoding Downset codes over a finite grid
摘要:
在最近的一篇论文中,Kim和Kopparty(计算理论,2017)给出了一种确定性算法,用于解决一般网格上有界全次数多项式的唯一解码问题。我们表明,他们的算法可以适用于解决一般家庭的Downset码的唯一解码问题。在这里,下集码由在取因子下闭合的单项式族D指定:对应的码是所有多项式的求值空间,这些多项式可以被写为来自D的单项式的线性组合。
英文摘要:
In a recent paper, Kim and Kopparty (Theory of Computing, 2017) gave a deterministic algorithm for the unique decoding problem for polynomials of bounded total degree over a general grid. We show that their algorithm can be adapted to solve the unique decoding problem for the general family of Downset codes. Here, a downset code is specified by a family D of monomials closed under taking factors: the corresponding code is the space of evaluations of all polynomials that can be written as linear combinations of monomials from D.
