| Abstract: | In the blue-green laser submarine communication,the time-frequency shift keying(TFSK) is used to make the system good characteristics of resistance to frequency selective fading,and application of turbo code which has strong error correction ability will further improve the system performance.This paper takes the blue-green laser submarine communication system as a platform,the TFSK technology based on Turbo codes was studied deeply.The side-correlation algorithm was used in demodulation of TFSK,so the wire... |
