열잡음과 부분대역재밍이 존재하는 레일레이 페이딩 채널에서 오류정정부호와 다이버시티를 고려한 FH/CPFSK 시스템의 성능분석

Performance analysis of FH/CPFSK system with the error-correcting code and the diversity under rayleigh fading channel with the thermal noise and the partial-band noise jamming

In this paper, the performance for FH/CPFSK system with limiter-discriminator detection and integrage-and-dump post-detection filtering under thermal noie, partial-band noise jamming and rayleigh fading have been analyzed. The method of hard-decision diversity of which the transmitter repeated L times on different hops for each data symbol in a way to mutigate the effects of the jamming has been applied, and the receiver has been combined the L chips. Also, error-correcting code have been applied for improving performance of system. The thermal noise and partial-band noise jamming, intersymbol interference for all eight of the possible adjacent bit data patterns, and FM noise click for evaluating systems have been considered. Also optimum parameters to improve performance of FH/CPFSK system have been obtained and validities have been proved through computer simulation.
