Abstract

In this paper, we proposed a simple modification on Fiebig's REC algorithm for multiuser detection of FH/MFSK systems replacing hard limiter with soft limiter. The performance improvement of our modified REC algorithm has been confirmed with computer simulations. for the parameter of interest, the capacity could be increased about 5% or more without degrading the reliability.

본 논문에서는 FH/MFSK(Frequency-Hopping Multilevel FSK) 시스템의 다중사용자 검출 방법으로서 경판정 리미터 대신 연판정 리미터를 사용한 변형된 Fiebig의 REC(REduction of the number of Candidate symbols) 알고리즘을 제안하였다. 이 변형된 REC 알고리즘의 성능은 전산 실험으로 확인되었다. 고려한 시스템 변수에 대하여 시스템 용량은 같은 오류확률에서 기존 알고리즘에 비해 약 5% 내외로 증가되었다.
