PROCEDE DE RECEPTION DE SIGNAUX A ETALEMENT DE SPECTRE AVEC CORRECTION DE DECALAGE EN FREQUENCE, ET RECEPTEUR CORRESPONDANT

摘要

The invention concerns a method for receiving spectrum spread signals with frequency offset correction. The invention is characterised in that it consists in: estimating the modulation period related to Doppler effect by using a preamble and in producing a correction signal; then in correcting the signal transmitting the information by said correction signal. The digital signals are operated in base band using DOT and CROSS components. The invention is applicable to digital transmissions.
