Abstract

We design and analyze the bit interleaved coded modulation(BICM) for noncoherent N-symbol continuous phase frequency shift keying(CPFSK) on the interleaved Rayleigh fading channel. In this paper, we use the equivalent normalized squared distance(ENSD) of noncoherent N-symbol CPFSK to design and analyze the BICM system. Specially, we design the BICM system for noncoherent 2-symbol 4-ary CPFSK, and analyze the performance of the system by using the ENSD. Simulation results are also provided to verify the theoretical performance analysis.

인터리브 된 레일리 페이딩 채널에서 비동기식 N-심볼 연속 위상 주파수 변조(Continuous Phase Frequency Shift Keying, CPFSK) 방식을 위한 비트 인터리브 된 부호화 변조(Bit Interleaved Coded Modulation, BICM) 시스템을 설계하고 성능을 분석 하였다. 본 논문에서는 BICM의 설계와 성능 분석을 위하여 비동기식 N-심 볼 CPFSK의 기하학적 등가 정규 제곱 거리(Equivalent Normalized Squared Distance, ENSD)를 사용하였다. 특히 비동기식2-심볼 4진 CPFSK 방식을 위한 BICM 시스템을 설계하였으며, 이 시스템 의 성능을 ENSD를 이용하여 분석하고, 모의실험을 통해 검증하였다.
