ABSTRACT:
A method for reducing the synchronization overhead in Frequency Hopping communication systems. Generally, the method establishes a synchronization state during which a plurality of communications can take place without re-synchronization before each separate transmission. More particularly, the method establishes a synchronization period during which all the radios are initially synchronized, followed by a series of acknowledgment period and transmission periods during which any unit intending to transmit is assigned a specific time slot for such transmission.
