| 2 | Nonlinear codes with asymptotic parameters better than the Gilbert-Varshamov and the Xing Bounds显示文摘In this paper, we show that the Gilbert-Varshamov and the Xing bounds can be improved significantly around two points where these two bounds intersect by nonlinear codes from algebraic curves over finite fields. | HU Wanbao Department of Mathematics, Anqing Teachers College, Anqing 246011, China National Mobile communications Research, Southest University, Nanjing 210096, China | 2006 | Science China Mathematics2006，49，6： | 1 |
