Abstract

In this paper, it was estimated the BER performance of the individual system type by applying the SFH type and the FFH type to the FH MC-DS CDMA system that combined the strong points of MC DS/CDMA and that of Frequency Mewing under the Nakagami fading channel with Multi-tone Jamming. An increase in the number of hoppings means that it can improve theBER performance by reducing the receiving burden of the FH MC DS/CDMA by achieving a frequency diversity effect. Therefore, I verified that the performances of the FH MC DS/CBMA system could be impoved by increasing the number of hoppings.

본 논문에서는 Multi-Carrier 방식중의 하나인 MC DS/CDMA 방식과 대역확산 방식중의 하나인 주파수 호핑 방식을 결합한 FH MC-DS CDMA 시스템에서 SFH와 FFH를 적용하여 나카가미 페이딩 채널 하에서 멀티톤 재밍을 고려하여 시스템의 BER 성능을 비교 $\cdot$ 분석하였다. 호핑 횟수가 증가된다는 것은 주파수 다이버시티의 효과를 얻을 수 있게 되어 수신측의 부담을 줄이면서 FH MC DS/CDMA 시스템의 BER 성능을향상 시킬 수 있다는 것을 의미한다. 따라서 호핑 횟수를 증가시킴으로써 FH MC/DS CDMA 시스템의 성능을 개선할 수 있음을 입증하였다.
