163127306韩峰 物理上行控制信道符号的产生
- 物理上行控制信道PUCCH,用于承载上行链路控制信息,根据所承载的上行控制信息的不同,LTE物理层支持不同的PUCCH格式,采用不同的发送方式。(The physical uplink control channel PUCCH is used to carry uplink control information. According to the different uplink control information, LTE physical layer supports differe
MIMOOFDMPrecoding
- TD-LTE下行传输采用了MIMO-OFDM的物理层构架,通过最多4个发射天线并行传输多个(最多4个)数据流,能够有效地提高峰值传输速率。LTE的物理层处理过程中,预编码是其核心功能模块,物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by u
