ABSTRACT:
A system for synchronizing a spreading sequence transmitted during a plurality of time slots includes a plurality of communication stations. Each communication station includes: (a) a control unit; (b) a spreading sequence unit for originating the spreading sequence; (c) at least one of a transmitter and a receiver; (d) at least one delay unit responding to the control unit for imparting a first delay to the spreading sequence presented to the transmitter unit and responding to the receiver unit for imparting a second delay to the spreading sequence presented to the receiver unit; and (e) a synchronizing sequence generator coupled with the transmitter unit. The synchronizing sequence unit in a first station presents a synchronizing sequence for transmission accompanying spread information transmitted during selected time slots. A receiver unit in a second station employs the synchronizing sequence in cooperation with the spreading sequence for despreading received spread information.
