| Abstract: | The multi-tone interferences suppression in HF serial data transmission systems is analysed. Analytic expressions for the tap weights and minimum mean square errors of adaptive equalizer in HF serial systems are obtained. The rate of convergence of equalizer in the presence of multi-tone interferences is analysed. The analytic and simulated results indicate that the equalizer in HF serial systems can not only track the rapid variation of HF channel but also suppress the multi-tone interferences perfectly. |

| Keywords: | HF serial data transmission systems Multi-tone interferences Adaptive equalizer |
