diversity combining meaning in Chinese
分集合并
Examples
- It has good computational cost because of avoiding any inverse operation and optimal ordering . it also utilizes double - directional detection and diversity combine technology to migrate the error propagation , and then improve the ber performance
它不需要进行任何形式的矩阵求逆运算和最优信号排序操作,因此具有良好的算法复杂度,同时它利用双向检测策略与分集合并技术来抑制误差传递,提高了算法的检测性能。 - Space - time codes can be divided into tree mainly parts : bell layered space - time architecture ( blast ) , space - time trellis codes ( sttc ) and space - time block codes ( stbc ) . in this paper , we mainly compare the performance of blast and stbc in many aspects , such as design criterion , transmission rate , diversity gain , diversity combining , bit error rate and channel capacity etc . in this paper , we first respectively analysed the instantaneous received symbol energy - to - noise ratio of v _ blast in the diversity combining methods of maximal ratio combining ( mrc ) , equal gain combing ( egc ) and selective combing ( sc )
Mimo技术核心是空时编码( stc ) 。空时编码主要分为三种:分层空时码( blast ) 、空时格码( sttc )和空时块码( stbc ) 。本文主要对分层空时码和空时块码这两种编码方式在设计准则、传输速率、分集增益、接收合并、比特差错率和信道容量等方面进行了较为详尽的研究。 - Because of the structure of the traditional polarization diversity and combining scheme is too complex , after researching the polarization diversity and diversity combining technology , a new structure of receiver is proposed . in this structure the uniform sampling second - order dpll is used to remove the frequency bias after frequency discrimination
该结构控制较为复杂,为此结合实际项目要求,在研究了极化分集接收关键技术的基础上,提出了一种改进的极化分集接收机结构,即在鉴频之后利用均匀采样二阶数字锁相环误差传递函数的高通特性去除各种频偏分量。
