Hello everyone,

I just started using the OFDM reference design in simulation. I observed that the BER when the fullRate is set to 16-QAM (modMask_antA = 4) reaches 13.18% with SNR=500dB. I did no further modifications to the design than changing the modMask_antA in ofdm_tx_mimo_init.m. The BER using QPSK becomes zero after some packets. Is that a common value? Is there a configuration parameter I missed?  What would be the expected BER when using coded OFDM?

Thanks!
