2018-04-04 Thread Shane Petcavich via USRP-users
Hi, I'm using the B210 with Matlab's usrp integration. I have an issue which I can't seem to fully understand. I'm preparing ofdm data to send which is between +/- 1. However the data transport type on matlab says int16 (assuming its signed). So should I be scaling my data I'm sending to the USRP
