Patent ID: 7831002

Claim:
A system for effecting signal synchronization for employing a pseudonoise spreading sequence for spreading transmitted information during a plurality of successive time slots; the system comprising: a plurality of communication stations; each respective communication station of said plurality of communication stations comprising: (a) a control unit; (b) a spreading sequence originating unit coupled with said control unit for originating said spreading sequence; (c) at least one of a transmitter unit and a receiver unit; said transmitter unit and said receiver unit being coupled with said spreading sequence originating unit and coupled with said control unit; (d) at least one delay unit coupled with said transmitter unit and coupled with said spreading sequence originating unit; said at least one delay unit responding to said control unit for imparting a first delay to said spreading sequence presented to said transmitter unit; said at least one delay unit responding to said control unit for imparting a second delay to said spreading sequence presented to said receiver unit; and (e) a synchronizing sequence originating unit coupled with said transmitter unit; said synchronizing sequence originating unit in a first communication station of said plurality of communication stations having a first transmitter unit presenting a synchronizing sequence for transmission by said first transmitter unit accompanying spread information transmitted during selected time slots of said plurality of time slots; a second receiver unit in a second communication station of said plurality of communication stations employing said synchronizing sequence in cooperation with said spreading sequence for despreading received said spread information.
