It is more ; useful on an academic perspective for people trying to understand the DAB ; modulation. ; ; Mode 'max' is the normalization of every OFDM symbol. No overshoot, no ; truncating, but varying output power (around 3dB) which might not be the best ; for some power amplifier. The output samples are limited to a magnitude ; of 32768. ; ; Mode 'var' uses the method specified in ETSI 300 798 Clause 5.3. This method ; normalizes to 4 times the standard deviation for an approximation of the RMS ; power. So around 6/100000 samples will be truncated and will introduce some ; really minor distortion. But this mode also maximizes the output power. This ; is the gain mode recommended for real world operation as it is based on a DAB ; standard; the only difference is that ODR-DabMod internally calculates this with ; 32-bit floats instead of 8 bits. gainmode=var ; ; In mode var, you can choose to normalise the samples to something else than ; 4 times the standard deviation. ;normalise_variance=4 ; Transmission mode ; If not defined, use Transmission Mode 1 ;mode=1 ; The digital gain is a value that is multiplied to each sample. It is used ; to tune the chain to make sure that no non-linearities appear up to the ; USRP daughterboard programmable gain amplifier (PGA). ; If there is clipping, the spectral quality of the signal will quickly deteriorate, ; and wide-band noise will be generated. ; ; Be aware that there is a dependency with resampling. digital_gain=0.8 ; Output sample rate. Values other than 2048000 enable ; resampling. ; Warning! digital_gain settings are different if resampling ; is enabled or not ! rate=2048000 ; (DEPRECATED) CIC equaliser for USRP1 and USRP2 ; These USRPs have an upsampler in FPGA that does not have a flat frequency ; response.
