Receiver Hop-Error Correction for Differential Frequency Hopping
Stephen Fahey,Lim Nguyen 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.2
Differential Frequency Hopping (DFH) is a spread-spectrum communication technique in which the current hop frequency is determined by a Frequency Transfer Function (FTF) that relies upon the current data symbol and previous hop frequency. Channel noise may cause a detected hop frequency to be received in error. This paper proposes a method which utilizes knowledge of the hopping scheme to correct for receiver hop errors and improve system performance.
Dynamic Frequency Transfer Function for Differential Frequency Hopping System
Stephen Fahey,Lim Nguyen 한국통신학회 2020 한국통신학회 학술대회논문집 Vol.2020 No.11
Differential Frequency Hopping (DFH) is a spread-spectrum communication technique in which the current hop frequency is determined by a Frequency Transfer Function (FTF) that relies upon the current data symbol and previous hop frequency. This paper proposes a new dynamic FTF technique with wider spreading bandwidth for improved performance against an intelligent eavesdropper while keeping complexity low.
