Patent ID: 7099422

Claim:
A method of initial synchronization, or acquisition, of a radio frequency (RF) burst transmission comprising the steps of: generating at a transmitter a transmitted-reference preamble; transmitting by the transmitter a transmitted-reference, delay-hopped (TR/DH) burst to a receiver; detecting at the receiver the TR/DH burst to generate a time mark; following the transmission of the TR/DH burst, waiting by the transmitter a fixed period of time, the duration of which is known to the receiver, wherein the TR/DH burst comprises a code word consisting of N c chips, transmitted sequentially, having a fixed duration, T c , each chip being composed of N p pulse pairs; after the expiration of the fixed period of time, transmitting by the transmitter a burst of modulated RF bearing transmitted message data; and using by the receiver the generated time mark to begin reception of the burst of the RF burst transmission from the transmitter.
