Abstract
In this paper, we propose a new Compressed Differential Frequency Hopping(C-DFH) system over traditional Differential Frequency Hopping(DFH) system. In the receiver part of DFH system, it needs to detect all the possible frequencies in the bandwidth, which makes the spectrum resource become the technological bottleneck of DFH. However, the proposed C-DFH system can compress the bandwidth of spectrum by using non-orthogonal signals. The performance analysis in Additive White Gaussian Noise(AWGN) is given with the corresponding numerical results and simulation. All these prove that the performance of the C-DFH system is better than the traditional DFH system in the same bandwidth.
