- W2029144529 abstract "Chaos communication system can improve a system security due to characteristics of non-periodic, non-predictability, broadband signal and easy implementation. Also, chaos signal is sensitive to initial conditions of chaos map. By these reasons, security of chaos communication system is superior to digital communication system. BER performance of COOK modulation system is better than other chaos modulation systems, even if COOK modulation system uses an asynchronous receiver. However, security and safety of COOK modulated signal are worse than other chaos modulation systems, because information bits can be easily predicted from COOK modulated signal. In this paper, for security improvement of COOK modulated signal, we propose a novel Scrambling COOK modulation system by applying the scrambling method. Conventional COOK modulated signal can be predicted, because chaos signal is generated when data is only 1. However, proposed system cannot be predicted, because chaos signal is generated when data is 0 or 1. Therefore, security and safety of transmitted signal in scrambling COOK modulation system is superior to conventional COOK modulation system. 논문 14-39A-06-01 The Journal of Korea Information and Communications Society '14-06 Vol.39A No.06 http://dx.doi.org/10.7840/kics.2014.39A.6.303 303 ※ 이 논문은 2012년도 정부(교육과학기술부)의 재원으로 한국연구재단의 지원을 받아 수행된 기초연구사업임(No. 2012017339) First Author:Department of Electronic Engineering, Chungbuk National University, toogee89@nate.com, 학생회원 ° Corresponding Author:Department of Electronic Engineering, Chungbuk National University, ecomm@cbu.ac.kr, 정회원 * SK Telecom, danny92@nate.com, 정회원 ** 한국전파진흥협회, hskeum@rapa.or.kr, 정회원 논문번호:KICS2014-03-098, Received March 21, 2014; Revised June 3, 2014; Accepted June 3, 2014 The Journal of Korea Information and Communications Society '14-06 Vol.39A No.06" @default.
