ODR-DabMod

Revision as of 02:05, 28 November 2009

CRC-DabMod is the DAB OFDM modulator command developed by Communication Research Center (CRC) from Canada. It is free but not open source yet.

CRC-DabMod take an ETI (Ensemble Transport Interface) stream as input and output a complex baseband stream of samples with a default sampling frequency of 2.048MHz.

Example:

CRC-DabMod ./racor.eti -l -g1 -r3200000 

get racor.eti file, perform OFDM modulation on baseband at a sampling frequency of 3.2MHz. Output is sent to the standard output if not redirected or piped to another command (CRC-Dwap.py in general)

Usage

Usage:

	CRC-DabMod [input [output]] [-c clockrate] [-f] [-g gainMode] [-h] [-r samplingRate]

Where:

input:    ETI input filename (default: stdin).
output:   COFDM output filename (default: stdout).
-c:       Set the DAC clock rate.
-f:       (deprecated) Set fifo input.
-g:       Set computation gain mode: 0 FIX, 1 MAX, 2 VAR
-h:       Print this help.
-l:       Loop file when reach end of file.
-r:       Set output sampling rate (default: 2048000).
