COFDMTV is based on COFDM (coded orthogonal frequency-division multiplexing) technology: - 160 ms long OFDM symbols - 6.25 Hz per sub-carrier - 1/8 guard interval - differentially encoded PSK (phase-shift keying) modulation - systematic polar codes for forward error correction Following modes are supported: Using SPC(64800, 43072): Mode 6: 8PSK, 2700 Hz BW and about 10 seconds long Mode 7: 8PSK, 2500 Hz BW and about 11 seconds long Mode 8: QPSK, 2500 Hz BW and about 16 seconds long Mode 9: QPSK, 2250 Hz BW and about 18 seconds long Using SPC(64512, 43072): Mode 10: 8PSK, 3200 Hz BW and about 9 seconds long Mode 11: 8PSK, 2400 Hz BW and about 11 seconds long Mode 12: QPSK, 2400 Hz BW and about 16 seconds long Mode 13: QPSK, 1600 Hz BW and about 24 seconds long Payload must be smaller or equal to 5380 bytes.
