In a communication system, containing several transmitter with special identification code and at least one receiver, each of the transmitters generates a message, whilst the transmitters transmit the message almost concurrently. In each of the transmitters transmission of messages is delayed for the period of delay, equivalent to its identification code. Messages may be signals with the spread spectrum with the spread by direct progression, bits of which have stabile duration, whilst the established delay is equal to the said pre-determined duration of one bit of pseudo-random progression or longer than this duration. Additionally to the established delay as the first randoming delayed message can be modulated by selected second pseudo-random code progression, which is selected at random from the pre-determined set of pseudo-random code progression and to the transmitted signal as a channel second randoming is established. Other randomings can be established to lower often occurrence of message collisions received in receiver. |
