图3-74 接收机基带VHT-Data Demapper数据流示意图 此模块的输入是Equalization之后的数据,输出的是QAM调制每个bit的软信息LLR(Log Likelihood Ratio)。 如前所述一个通信收发系统可以简化表示以下关系: 其中y为某个频点上接收的信号,x为对应频点的发射信号,h为复平坦衰落信道在该频点上的频域响应, z 为加性高斯...
Comcores Radio Over Ethernet Structure Agnostic Mapper/Demapper IP core is a silicon agnostic implementation of the structure agnostic mapping method described in the IEEE 1914.3 standard. The RoE IP-core takes multiple streams of CPRI data and map these into one or several 10G/25G Ethernet data...
