ETSI EN 300 744 compliant DVBT encoder library written in c++ (except for hierachical transmission)

required libraries:

• libfftw3f
• libstdc++
• libpthread (workaround for g++ bug)

Supported Modes:

• Only hierarchical mode is supported
• IFFT size 8K and 2K
• coderate 1/2, 2/3, 3/4, 5/6, 7/8
• modulation QPSK, 16QAM, 64QAM
• guard interval 1/4, 1/8, 1/16, 1/32
• oversampling 1x,2x,4x,8x,16x
• output format
• complex float
• complex short (int16_t)
• complex ushort (uint16_t)
• complex char (int8_t)
• complex uchar (uint8_t)
• set output gain [float]

Note:

• For 64QAM 4x oversampling is recommended !

Tested Modes:

• IFFT size 2K, 8K
• coderate 1/2, 2/3, 3/4
• modulation QPSK, 16QAM, 64QAM
• guard interval 1/4, 1/8, 1/16, 1/32
• oversampling 1x, 2x, 4x
• output format float, signed short

TODO:

test coderate 5/6, 7/8
