Matlab 5G模块学习

 资源网格中的每一个元素就叫做资源元素(Resource Element)， 它是上下行传输中的最小资源单位。
Resource blocks（资源块）
频域上连续12个连续的子载波被称为一个资源块，对于μ=1的国内运营商来说，一个资源块频域上市360KHZ.

simulink信号流仿真，信号数据类型
软件和硬件联合调试，或者软件和EDA软件联合调试

HARQ：混合自动重传请求（Hybrid Automatic Repeat reQuest，HARQ），是一种将前向纠错编码（FEC）和自动重传请求（ARQ）相结合而形成的技术。
循环冗余校验码 (CRC)
这是我关心的部分：
Carrier and PDSCH Configuration
Set the key parameters of the simulation. These include:

The bandwidth in resource blocks (12 subcarriers per resource block).

Subcarrier spacing: 15, 30, 60, 120 (kHz)

Cyclic prefix length: normal or extended

Cell ID

Number of transmit and receive antennas

A substructure containing the DL-SCH and PDSCH parameters is also specified. This includes:

Target code rate

Allocated resource blocks (PRBSet)

Modulation scheme: ‘QPSK’, ‘16QAM’, ‘64QAM’, ‘256QAM’

Number of layers

PDSCH mapping type

DM-RS configuration parameters

PT-RS configuration parameters

Other simulation wide parameters are:

Propagation channel model delay profile (TDL or CDL)

SS burst configuration parameters. Note that the SS burst generation can be disabled by setting the SSBTransmitted field to [0 0 0 0].

Propagation Channel Model Construction
Create the channel model object for the simulation. Both CDL and TDL channel models are supported .
