부분대역 재밍하에서 열잡음과 오류정정 부호를 고려한 FH/MFSK 시스템의 성능 분석 = Performance Analysis of the FH/MFSK Considering Thermal Noise and Error Correcting Code under the Partial-band Jamming

다국어 초록 (Multilingual Abstract)

In this paper, the performance is analyzed in noncoherent frequency hopping-frequency shift keying(FH/FSK) system in which the error correcting codes are adopted and thermal noise is cosidered under the partial-band jamming interference.
In consideration of thermal noise under the partial band jamming, the system performance is analyzed by applying the closed-from of error probability. As a result, it is shown to be valid via the computer simulation that the more is K and E_(b)/N_(o), the less is error probability.
The error performances of binary correcting codes which adopt the uncording method, block coding and convolutional coding methods are analyzed to be evaluated in worst case of the partial band jamming interference.
Among the three coding methods, it is proved that the best performance of bit error probability is found in the convolutional code(rate : 1/8).
These results may be useful for avoiding the common vulnerabilities when the spread spectrum system is designed.
