Patent ID: 7684466

Claim:
A wired spread spectrum communication device comprises: a wired information signal port which introduces information signals consisting of base bands into wired channels, a sine wave signal generator which generates specified sine wave signals; an information spread spreading means comprising a spread code generating means and a modulator for each channel, which generates spread spectrum signals for spreading said information signals on the basis of specified spreading codes by multiplying said specified spreading codes, a sync signal generating means comprising a sync spread code generating means, a modulator and a timing gate, which intermittently outputs spread spectrum signals that have been generated by the sync spread code generating means and modulated by multiplying with said sine wave signals by said modulator, at specified timings controlled by said timing gate as sync signals, a superposing means which superposes the sync signals that have been output from the sync signal generating means to the spread information signals, and a transmitting means which sends the spread information signals, which have been superposed with the sync signals by the superposing means, to wired transmission paths.
