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。
