<p>A method for radio communications providing propagation of information radio signals, transmitted by information sources, their receiving and demodulation by a receiver equipped with an antenna, characterized in that the information sources radiate additional pilot signals, available by one of the known methods of radio access, and the phase shifts among the signals, provided by the different antenna elements, is random regardless of the information sources directions, and the pilot signals are recovered from the receiver output signals, and the pilot signals correlate with the phase spread information signals in order to recover the information signal, and the latter is demodulated. A system for radio communications comprising sources of information radio signals, antenna, receiver and demodulator, characterized in that:- the sources of information signals (1) provide transmission of information modulated signals and additional pilot signals, available in the receiver by one of the known methods of radio access such as FDMA, TDMA or CDMA;- the antenna (2) is an antenna array with elements, distributed in such manner, that the phase shifts among the signals, provided by the different elements, are random regardless of the information sources (1) directions to the antenna (2);- the output of the antenna (2) is connected to the input of the receiver (3), its RF or IF output is connected to the input of the pilot recovery subsystem (4) and to the first input of the correlator (5), its second input - to the output of the pilot recovery subsystem (4);the output of the correlator (5) is fed to the demodulator (6).</p> |
