METHOD OF TRANSMITTING DISCRETE MESSAGES OVER WIRELESS COMMUNICATION CHANNELS Russian patent published in 2009 - IPC H04B7/00 

Abstract RU 2377723 C2

FIELD: physics; communications.

SUBSTANCE: invention relates to wireless communication and can be used in wireless communication systems using absolute (worldwide and system) accurate time. The method of transmitting messages over wireless communication channels involves constant clock and cycle synchronisation of the transmitter and receiver regardless of message transmission and the keying rate used provides for duration of message elements which is many times longer than signal propagation time or possible difference in signal propagation time from the transmitter to the receiver, and transmission of each next message element begins at a predefined moment of absolute worldwide and/or system accurate time. Also transmission of each next message character begins at predefined moments in absolute worldwide and/or system accurate time, and the signal propagation time from the transmitter to the receiver is determined and at the transmitter a message is formed ahead by signal propagation time or in the receiver moments for deciding on value of received elements and characters are delayed by signal propagation time.

EFFECT: increased noise immunity of the communication system.
