Abstract:
A method for spread-spectrum communication between a first transceiver and a second transceiver, the method comprising the steps of:transmitting, from a spread spectrum transmitter associated with the first transceiver to a spread spectrum receiver associated with the second transceiver, a spread spectrum preamble;transmitting, from said spread spectrum transmitter to said spread spectrum receiver, a spread spectrum encoded data message immediately following said spread spectrum preamble, said spread spectrum encoded data message separated in time from said spread spectrum preamble by a predefined gap during which the second transceiver does not transmit to the first transceiver;receiving said spread spectrum preamble at said spread receiver;generating, at said spread spectrum receiver, a correlation signal in response to said spread spectrum preamble;receiving said spectrum encoded data message at said spread spectrum receiver; anddespreading said spread spectrum encoded data message at said spread spectrum receiver.
