Hello ,I am bradcasting a file called NR_40M_30KHz_FS46po8M_106RB_CP-256QAM at 3.6GHz carrier frequency.
From the file i understand that our BW is 40MHz ,the sub carrier spacing is 30Khz at QAM 256.
I have set in my device as shown in the attached photos and in the live VIDEO link i made.
As you can see my constalation is glitching and its a blob ,Is there some thing i could do to see a clear consltalation or improve the situation ?
Thanks.
