Could anyone expand on Mike's answer regarding the use of UHD via MATLAB and clearly state the numerical for the following: minimum value of I data for transmitmaximum value of I data for transmitminimum value of Q data for transmitmaximum value of Q data for transmitminimum value of I data for receivemaximum value of I data for receiveminimum value of Q data for receivemaximum value of Q data for receive From: Mike.McLernon@mathworks.com To: cystrin@hotmail.com CC: Darel.Linebarger@mathworks.com; Marc.Erickson@mathworks.com; Ethem.Sozer@mathworks.com; usrp-users@lists.ettus.com Subject: RE: USRP :: MATLAB's comm.SDRuTransmitter Date: Mon, 25 Mar 2013 15:02:59 +0000 Hi Stan, The MATLAB code for comm.SDRuTransmitter does not perform any range checking on its inputs. So the object itself will accept any double values. Any range checking would be performed by the underlying UHD code.

The input signal, X, is a column vector of double values. What range has X--what are its minimum and maximum values? Thanks, Stan
