一种基于递归逆的快速盲均衡算法

自适应调度是以满足系统某一性能指标要求为目的,对数据查询中的算子进行动态调度的系统优化技术。针对选择查询中可交换顺序的条件过滤器的排序问题,设计了自适应过滤器排序算法,它以静态贪心算法为基础,通过滑动窗口机制模拟出过滤器之间的条件选择性特征,构建了一个条件概率关系矩阵,以指导过滤器排序的动态优化,得到一个当前条件下处理开销最低的过滤器排序,在较低的运行开销条件下,提升了系统的处理能力。

Fast Blind Equalization Algorithm Based on Recursive Inverse Algorithm

Adaptive scheduling is a system optimization technique to dynamically schedule the operators in a query plan for the purpose of meeting certain performance specifications.An adaptive ordering algorithm based on the static greedy algorithm is designed to deal with the problem of sequencing the commutative filters in a select query.By modeling the characteristics of conditional selectivity between the filters with a sliding window,a relational matrix filled with conditional probabilities is built,and the sequ...
