무선 채널을 위한 CPM 의 비동기 검출 방식에 대한 연구 = Non-coherent Detection of Continuous Phase Modulation

다국어 초록 (Multilingual Abstract)

In this paper, we consider a maximum likelihood(ML) non-coherent detection sch-me for multiple symbol continuous phase frequency shift keying (CPFSK) for the
wireless communication channel. By utilizing a Gaussian approximation for Rician ra-ndom variables, we express the pairwiserror probability as a function of the equivale-nt normalized squared distance(ENSD). ENSD plays the same role as normalized sq-uared Euclidean distance when evaluation error probability performance for coherent
detection. We derive an analytical approximation on the bit error probability by empl-oying ENSD for the uncoded system. For the uncoded system we show that the bit
error probability of noncoherent detection approaches that of coherent symbol-by-sy-mbol detection in the limit as the symbol goes to infinity for large SNR.
