PROBLEM TO BE SOLVED: To provide an SS communication apparatus which enables simplification of the structure, reduction in size and weight, power savings, and reduction in cost, and can exchange images, voices, and data by transmission/reception using the half-duplex operation of information signals, such as images, voices, data, and ID code signals. SOLUTION: This SS communication apparatus has a means which modulates/ demodulates image signals and voice signals, which are information signals, mixes prescribed ID code signals with data communication signals; and after being subjected to spectrum spread/reverse spread, it transmits the signals with prescribed carrier frequencies and receives the signals, and a decision means (an SAW convolver 59, 1, 2 CH separator 53, etc.), which receives ID code signals after spectrum spread as the input signals of the SAW convolver 59 and receives prescribed reception control signals from a reception control signal input unit 76, as the SS reference signals of the SAW convolver 59 for spectrum reverse spread, demodulates the ID code signals, and decides whether the demodulated ID code signals are prescribed ID code signals. |
