Application of maximum minimum value of quadratic function 二元函數(shù)條件極值的一個(gè)簡便判別方法
Through a performance analysis and simulation on generated methods , maximum minimum distance , undetected error probabilities , code weight distribution , good extended shortened codes are determined and general rule is concluded . furtherly , the paper generates nonlinear extended shortened codes 通過對擴(kuò)展縮短crc碼的構(gòu)造方法、最小距離、不可檢錯(cuò)誤概率、碼重分布等進(jìn)行理論分析和仿真,得到了擴(kuò)展縮短crc碼的好碼,并綜合出普遍規(guī)律。
