MATLAB: 3GPP 5G Link Level Modeling Using TDL/CDL Propagation Channels

5Glte system tool boxwireless

How can we calculate the Bit Error Rate and Packet Error Rate using the example file 3GPP 5G Link Level Modeling Using TDL/CDL Propagation Channels please?

Thanks

The 5G NR throughput simulation is implicitly recording the transport block BLER/PER via the blkCRC variable (this indicates whether each block (including retransmissions) was received in error or not) then scaling it by the block sizes to calculate the Mbps throughput.

MATLAB: Modify number of antennas in NR PDSCH Throughput

Hi Javier,

The one most important aspect is to change is the number of layers. The number of layers decide whether the number of codewords is set to 1 or 2. Though you made your simulation setup to NumCW as 2, if the NumLayers field is less than 4, it doesnt affect.

When the number of layers is greater than 4, there will be two codewords. When the number of layers is less than or equal to 1, there will be single codeword.

So the update required is;

simParameters.PDSCH.NLayers = 5;  % Any value greater than 4 and less than or equal to 8, to perform two codewords simulation

Hope this helps.

Regards,

Sriram
