码字序列 meaning in English

code word sequence

In 3 - d ocdma system , the code sequence for each user is spreaded in time chip , wavelength and space . compared with 2 - d ocdma system , 3 - d system can accommodate more total users and simultaneous users
三维ocdma系统中,每个用户码字序列的光脉冲同时在时间域、频率域和空间域扩展,三维系统较之二维系统拥有更大的总用户和同时激活用户的容纳能力,系统性能更好。
Ldpc code belongs to the linear block code which is encoded by the information sequence multiplies generator matrix . although the parity - check matrix of ldpc code is sparse , the generator matrix is not . the encoding complexity of it is linearly proportional to the square of code length
Ldpc码属于线性分组码,线性分组码的通用编码方法是由信息序列根据码的生成矩阵来求相应的码字序列,尽管ldpc码的校验矩阵是非常稀疏的,但它的生成矩阵却并不稀疏,这使得其编码复杂度往往与其码长的平方成正比。
