摘要
Recently Koy proposed primal-dual bases which have better quality than LLL-reduced bases in high-dimensional lattice, but his efforts did not take into account the low and upper bounds for the ratios of primal-dual bases to successive minima. In this paper some useful properties of Koy's primal-dual bases are analyzed and then the low and upper bounds for the ratios of primal-dual bases to successive minima are introduced and proved. At the end, the Round-off algorithm for the approximate-CVP is improved using primal-dual bases and its result has a better approximation factor than L. Babai's.
