基于和值不等式的快速码字搜索算法
Fast codeword search algorithm based on value and inequality
近些年来学者们针对传统码字搜索算法的缺点，提出的码字搜索算法有效地缩减了码字搜索的范围，且大大地减少了所耗费的时间。由于在进行搜索时，和值不等式的运用不需要进行计算，因此本文算法将其与矢量的范数和方差结合起来使用。仿真结果表明，和EEENNS算法相比较，本文提出的算法大大降低了码字搜索时的计算量，且计算时间相对减少。
In recent years, scholars being aimed at the shortcomings of traditional codeword search algorithm proposed some code word search algorithm.These code word search algorithm effectively reduced the scope of codeword search and greatly reduced the waste of time. In the search,the application of value inequality does not need to calculate,so this paper combines the vector norm with variance.The simulation results show that compared with the EEENNS algorithm,the algorithm proposed in this paper greatly reduces the computation of the code word search and less calculation time.
