| Abstract: | In order to to meet the ship and shore in the distance high speed data transmission, CMX909B and $3C2440 is used to design a marine high-speed wireless data transmission system. GMSK modulation characteristics and CMX909B chip features, and the system of modulation and demodulation circuits are introduced. The system can be employed in the short or VHF channel for accurate, real-time, high-speed wireless data transmission, and solve the middle-distance wireless communication problem of low data transfer rate. |
