<p><P>PROBLEM TO BE SOLVED: To provide a broad-band transmission communication system capable of separating and dividing television signals, other various data, and signals of these complex data in response to their frequency bands, modulating these separated signals by means of spread spectrum, transmitting these signals by using coaxial cables for television, and sending and receiving the signals to and from a terminal in a wired frequency band. <P>SOLUTION: In condominiums, buildings, hospitals, public facilities, factories, etc., the broad-band transmission communication system is established by conducting spread spectrum processing by a SAW convolver system by a SAW device on a coaxial cable network for TV connected between a television antenna and a television, and by modulating the signals. That is, a new transmission path and a new broad-band transmission communication system can be established economically without newly performing cable laying work. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
