Fading 채널 환경에 적합한 다중 심벌 트렐리스 부호화 비동기 CPFSK 방식 연구 = A Study on Multiple Symbol Trellis Coding Scheme for Noncoherent CPFSK

다국어 초록 (Multilingual Abstract)

In this paper, we introduce an encoder design technique of multiple symbol trellis coded modulation for noncoherent continuous phase frequency shift keying (MTCM/NCPFSK) on the interleaved Rician fading channel. To find dominant factors which affects the error probability of MTCM/NCPFSK, we derive the pairwise error probability (PEP) of MTCM/NCPFSK and find that the error probability mainly depends on the effective length of error event and the corresponding squared product distance for the small value of Rician paramenter K. Using this performance criteria, we search for the optimal encoder of MTCM/NCPFSK for the interleaved Rician fading channel. We also compare that encoder with the encoder designed for additive white Gaussian noise channel
