Abstract

Wireless transmission process and apparatus include a frequency diversity process for carrying out spectral spreading of a modulated SHF (Super High Frequency) carrier. The modulated SHF carrier transports information between a transmitter and at least one receiver. The frequency of the SHF carrier is varied continuously in a specified band so as to transmit to the receiver a signal having a spectrum containing a plurality of frequencies representing a plurality of uncorrelated signals each transporting the information to be transmitted.
