ABSTRACT:
A communication apparatus using a chaotic signal and a method thereof are provided. The communication apparatus includes a correlator which multiplies source data by one of an optical orthogonal code (OOC) and a prime sequence code (PSC), and outputs transmission data, a transmission signal generating unit which generates a chaotic transmission signal by masking the transmission data with respect to a chaotic signal, and an antenna which transmits the chaotic transmission signal. As a result, multiple accesses are enabled, and a wireless communication system for short-distance operation, which is economic and low power-consuming, is provided.
