| Abstract: | A new HF hopping system, which is called Differential Frequency Hopping (DFH) system, is presented in this paper. The main difference between DFH and traditional Frequency Hopping (FH) is induced detailedly. The perfor- mance of DFH system in AWGN channel with detection by sequence is analyzed in theory, and the corresponding simula- tion results are given. All these prove that the performance of DFH system with signal detection by sequence is much better than ordinary frequency hopping system in AWGN channel. |
