Abstract EN
This paper considers spectrally efficient differential frequency hopping (DFH) system design.
Relying on time-frequency diversity over large spectrum and high speed frequency hopping, DFH systems are robust against hostile jamming interference.
However, the spectral efficiency of conventional DFH systems is very low due to only using the frequency of each channel.
To improve the system capacity, in this paper, we propose an innovative high order differential frequency hopping (HODFH) scheme.
Unlike in traditional DFH where the message is carried by the frequency relationship between the adjacent hops using one order differential coding, in HODFH, the message is carried by the frequency and phase relationship using two-order or higher order differential coding.
As a result, system efficiency is increased significantly since the additional information transmission is achieved by the higher order differential coding at no extra cost on either bandwidth or power.
Quantitative performance analysis on the proposed scheme demonstrates that transmission through the frequency and phase relationship using two-order or higher order differential coding essentially introduces another dimension to the signal space, and the corresponding coding gain can increase the system efficiency.
