Abstract: A spread spectrum signal transmission method and spread spectrum signal transmission system in which a carrier frequency is frequency modulated with an analog or digital baseband signal in a transmitter, the frequency modulated carrier is converted into a pulse sequence, each pulse is converted into a band-spread signal linked with a code and transmitted via an antenna, and wherein the transmitted signal is subsequently received by an antenna and linked with a code which is the time inverse of the first named code, whereby a sequence of correlation peaks arises, which are converted into a pulse sequence and subsequently frequency demodulated to obtain an output signal corresponding to the analog or digital baseband signal. The method or the system make it possible to achieve an interference-free transmission of both analog and also digital signals with low transmitter power and/or large range, with a low number of system components, i.e. with simple and cost favorable system components.
