一种适用于WPAN应用环境的高速自适应跳频系统及其性能分析 总被引:8,自引:0,他引:8
本文针对无线个域网(WPAN,Wireless Personal Area Network)工作环境复杂的干扰情况,提出将自适应跳频技术应用其中的方案,并以几个WPAN系统为例进行了定量计算.得出了采用AFH技术后系统的误码特性,最后以802.15.1(Bluetooth)及802.15.3系统为例,对其主要的数据速率和1600跳/秒情况进行了数值计算.结果表明,在小区域内存在多种系统工作在同一频段的情况下,采用AFH技术的WPAN系统抗干扰性能差不多提高了1~2个数量级.本文结论也可推广到使用高速跳频技术的其它WPAN系统. 相似文献

修正的 Thiele-Werner型有理插值 总被引:1,自引:0,他引:1
Through adjusting the order of interpolation nodes, we gave a kind of modified Thiele-Werner rational interpolation. This interpolation method not only avoids the infinite value of inverse differences in constructing the Thiele continued fraction interpolation, but also simplifies the interpolating polynomial coefficients with constant coefficients in the Thiele-Werner rational interpolation. Unattainable points and determinantal expression for this interpolation are considered. As an extension, some bivariate analogy is also discussed and numerical examples are given to show the validness of this method. 相似文献

二元插值的一般框架的注记 总被引:2,自引:0,他引:2
Newton interpolation and Thiele-type continued fractions interpolation may be the favoured linear interpolation and nonlinear interpolation, but these two interpolations could not solve all the interpolant problems. In this paper, several general frames are established by introducing multiple parameters and they are extensions and improvements of those for the general frames studied by Tan and Fang. Numerical examples are given to show the effectiveness of the results in this paper. 相似文献
