But the school bell rang he again enchanted become a girl 's character .

可是上课 铃声一响，他就又被施了魔法，变成了女孩子的 性格。

Combining vertical bell laboratories layered space-time ( V-BLAST ) and multi-code code division multiple access ( CDMA ) is an effective way to improve data speed a good communication character can be obtained based on spreading codes with zero-correlation-window .

垂直 分层空时结构（VBLAST）与多码码分多址（CDMA）结合可显著提高通信系统的传输速率，而基于零相关窗互补码（LS码）的码分多址系统具有良好 特性。
