Summary A coherent, transparent optical communication system has been developed for free-space lasercomm terminals. The laser synchronisation scheme has been chosen such that the transmission of either an ensemble of subcarrier-modulated signals or of a binary baseband signal is equally possible. By using double-sideband modulation and an average-power-limited booster amplifier, the link capacity for subcarrier-multiplexed transmission approaches that of a homodyne PSK transmission system to within 0.5 dB. |
