NAME
odr-dabmod - DAB modulator compliant to ETSI EN 300 401
SYNOPSIS
odr-dabmod <configuration_file> odr-dabmod input (-f filename -F format | -u uhddevice -F frequency) [-o offset][-G txgain] [-T filter_taps_file] [-a gain] [-c clockrate] [-g gainMode] [-m dabMode] [-r samplingRate] [-l] [-h] Where input is: ETI input filename (default: stdin), or tcp://source:port for ETI-over-TCP input, or zmq+tcp://source:port for ZMQ input, or udp://:port for EDI input.
DESCRIPTION
ODR-DabMod is a software-defined DAB modulator that receives or reads ETI, and generates modulated I/Q data usable for transmission. It can directly interface the Ettus USRP devices, and can also be used with other SDR signal sources. This I/Q data which is encoded as complex floats (32bits per complex sample) can be written to a file or pipe, sent to a USRP device using the integrated output for the open- source USRP Hardware Driver (UHD) or to other software-defined radio (SDR) devices using the SoapySDR5 library. The output of the modulator can also be sent to a GNURadio flow-graph for further processing, conversion or analysis using a ZeroMQ network connection.
OPTIONS
-f Use file output with given filename. (use /dev/stdout for standard output) -F Set the output format (see doc/example.ini for formats) for the file output. -o Set the timestamp offset added to the timestamp in the ETI. The offset is a double. Specifying this option has two implications: It enables synchronous transmission, requiring an external REFCLK and PPS signal and frames that do not contain a valid timestamp get muted. -u Use UHD output with given device string. (use for default device) -F Set the transmit frequency when using UHD output. (mandatory option when using UHD) -G Set the transmit gain for the UHD driver (default: 0) -T Enable filtering before the output, using the specified file containing the filter taps. Use 'default' as taps_file to use the internal taps. -a Apply digital amplitude gain. -c Set the DAC clock rate and enable Cic Equalisation. -g Set computation gain mode: fix, max or var -m Set DAB mode: (0: auto, 1-4: force). -r Set output sampling rate (default: 2048000). -l Loop file when reach end of file. -h Print this help.
