最佳码 meaning in Chinese

optimal code
optimum code

Some results on the undetected error probability of linear codes for pure error - detection are , at present , generalized for both error detection and correction . an analytic formula is obtained to calculate the undetected error probability of linear block codes for simultaneous error detection and correction
在只检错时，证明了纠正两个错误扩展bch码是最佳检错码； m大于4的非线性等重码( 2m ， 2 ， m )不是最佳码。
The concept of good codes and proper codes for both error detection and correction is presented . it is shown that the binary perfect codes and the primitive double - error - correcting bch codes and their extended codes are proper for both error detection and correction . the primitive triple - error - correcting bch codes with length 2 " " - 1 and their extended codes are proper for odd m > 5 , not for even m > 6
本文的主要工作是把目前关于只检错时线性码不可检错误概率的研究推广到同时纠错和检错的情况，获得了同时纠检错时线性码不可检错误概率的解析表达式，提出了纠检错好码和最佳纠检错码的概念，并证明了二进制完备码及其扩展码是最佳纠检错码；纠正两个错误二进制本原bch码及其扩展码是最佳纠检错码；码长n = 2 ~ m - 1 、纠正三个错误本原bch码，当m为大于等于5的奇数时是最佳纠检错码；当m为大于等于6的偶数时，不是最佳码。
