When running the ARM library simulation, Turbo decoding works as expected, but LDPC does not. developer.arm.com/.../2310
We have experimented with differing values for demod_ulp, but this is the best performance we see. ARM RAL Turbo compares to MATLAB, LDPC falls waaaaaay short.
It appears that the ARM implementation of 5G LDPC is broken. We have initiated a support ticket, but received no response. Is anyone else seeing this?
Thank you for the case number, Dale. We will investigate the decoding performance issue -- I have been able to reproduce the sort of graph you have attached here.
