High efficiency planetary burst communication method and apparatus using spectrum spreading method

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Meteor Burst Communication (MBC) method, and a method of directly applying a Direct Sequence Spread Spectrum (DSSS) (PSK) to a pseudo-noise signal and transmits the spread spectrum signal by spreading it to a pseudo-noise signal, By adding the signal processing gain obtained by spreading to the S / N of the system, the threshold voltage can be lowered and the conduction time of the communication path can be lengthened, so that the microburst reflection signal below the detection noise power level can be received Is a very useful invention.
