Method For Sending And Receiving A Spread Spectrum Wireless Communication With High Potential Spectral Efficiency And Associated Devices

Abstract: The invention relates to a method for sending a wireless communication, the method comprising: obtaining symbols through channel coding and digital modulation; DSSS spreading of each symbol obtained with a spreading code of period TDSSS applied with a spreading factor, the SF chips spreading a symbol being specific to the time of sending of the symbol; and obtaining, from each symbol, a set of SF chips that are spread according to the value of the symbol, these chips being separated by a period; implementing, on the chip, the steps of: - compressing the period between the chips at a compression rate that is strictly greater than 1, the period between the chips after this compression being equal to ?Tc; - filtering by means of a shaping filter using square-root Nyquist filtering for orthogonality period Tc or a finite-length useful bandwidth.
