Read full description

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 Currently Modes 14, 15 and 16 are supported: Using either SPC(2048, 1392), SPC(2048, 1056) or SPC(2048, 712) with CRC32C aided SCL decoding and differential QPSK modulation for the payload. Only a bandwidth of 1600 Hz is needed and the transmission of either 85, 128 or 170 bytes take about one second with the leading noise and fancy header disabled.
