The Research on the Orthogonal Modulation Multiplexing in the Narrowband Wireless Data Transmission System
Aiming at the offing ship-to-shore wireless data transmission system has infects in the short transmission distance and low speed and so on, this paper presents a new feasible technical scheme of increasing the speed of the data transmissiom The scheme realizes orthogonal modulation multiplexing of a carrier transmitting two signals in the channel with same width by using the orthogonality of the carrier phase,adopting two DSB linear modulation and vector compounding, exacts simultaneous carrier direct when demodulating. Doubling the speed of the data transmission and frequency efficiency in the narrow band system , which meets the demands of the offing high speed data transmission system.
