LDPC Encoder/Decoder v2.0 5G EXAMAPLE DESIGN

Processor-based example design for LDPC Encoder/Decoder v2.0 IP is not working as excepted for 5G. I am using Vivado 2019.2.1 in windows. I get the same error count before and after the decoding for almost all SNR. Other configurations (default & wifi 802.11) are working fine. 5G in Example design for soft-decision FEC (1.1) IP is also working fine. I have attached the screenshot for the simulation and the example design parameters below. Can anyone guide me on this?

Hi nathanx,

Thank you for your response.

5G configuration in PS-based example design for LDPC Encoder/Decoder IP V2.0 is not working as excepted. I always get the same values for Bit error and uncorrected bit error after decoder.

Hi @thiru_ashok ,

Did you enable the interactive GUI mode and run the design ? what is the range of SNR that is checked here ?
