METHOD FOR TRANSMITTING INFORMATION BY MEANS OF CODE SIGNALS, INFORMATION TRANSFER SYSTEM FOR IMPLEMENTING THIS METHOD AND TRANSMITTER AND RECEIVER FOR USE IN THE TRANSMITTER SYSTEM.

摘要

A method of and system for transmitting n-bit information words is revealed, using code signals (Sc, xi) in which the bits (b1, b2, b3, b4) having corresponding bit positions in different information words are always represented by frequency components (fd1, fd2, fd3, fd4; fh1, fh2, fh3, fh4) in the same frequency range of the frequency spectra of the code signals (Sc, xi). Bits having different bit positions are represented by frequency components which are situated in different frequency ranges of the frequency spectra of the code signals. After transmission of the code signals the individual bits of the information words are recovered by means of frequency-domain detection.
