Wireless HDL Toolbox / Modulation
Description
这NR Symbol Demodulator基于5G新广播(NR)标准TS 38.211支持的调制类型,将复杂的数据符号解调为数据位或对数似然比(LLR)值(LLR)值金宝app[1]。这block provides an architecture suitable for HDL code generation and hardware deployment. You can use this block in the development of an NR receiver.
这block accepts data symbols, along with a valid signal, and outputs demodulated bits or LLR values with valid and ready signals. The number of demodulated bits or LLR values for a given symbol depends on the modulation type, as shown in this table.
调制类型 | 每个符号的位数(NBP) |
---|---|
BPSK | 1 |
qpsk | 2 |
16 Qam | 4 |
64-QAM | 6 |
256-QAM | 8 |
pi/2-BPSK | 1 |
这ready输出端口指示块何时可以接受输入数据样本。您可以使用ready输出端口以控制进入块的上游数据。
