摘要： Provided are a wide band-differential chaos shift keying modulation method, a transmitting apparatus adopting the wide band-differential chaos shift keying modulation method, a wide band-differential chaos shift keying demodulation method, and a receiving apparatus adopting the wide band-differential chaos shift keying demodulation method. The wide band-differential chaos shift keying modulation method includes: generating a wide band chaotic signal; delaying the wide band chaotic signal; multiplying the delayed wide band chaotic signal by an information signal to output a multiplied signal; and performing a switching operation so as to alternately transmit the wide band chaotic signal and the multiplied signal. Thus, the invention can be realized without an APLL, a mixer, an FM modulator, and the like, to reduce power consumption and manufacturing cost for the transmitting apparatus. Thus, noise characteristics and security performance can be high, and the wide band-DCSK modulation method can be robust to multi-path.

摘要： A method and apparatus for simplifying a structure needed to delay data in delay units when a reference signal and data are transmitted by using chaotic signals are provided. The method includes delaying data by at least two delay times, wherein each of the delay times occurs sequentially; multiplexing the data, which has been delayed, according to a control signal; and transmitting the data and a reference signal which corresponds to the data at an interval of delay time. The apparatus includes a first delay unit which is configured to delay data for a first delay time; a second delay unit which is configured to delay the data output from the first delay unit for a second delay time; and a multiplexer which is configured to multiplex the data from the first and second delay units according to a control signal.
