基于最优小波包基改善高速长输信号的完整性
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 10
Abstract
为了解决理想无损传输线理论在分析高速信号长距离输送时的不适用性的问题，将信号衰减因子引入高速长输信号的反射和串扰分析。围绕由不确定环境骚扰、反射和串扰噪声所引出的高频数字信号的完整性问题，通过对将自底向顶和深度优先相结合的最优小波包基搜索策略的探讨，采用数字仿真与实验数据相结合的方法，提出基于最优小波包基改善高速长输信号完整性的方法。数字仿真结果表明：最优小波包基方法消噪效果优于小波方法或普通小波包方法，可提高高频数字信号的边沿质量，有利于高速长输信号完整性的改善。
