| Abstract: | The application and realization of asymmetric multi-channel transceiver technology in HF emer- gency communication is described. The emergency command center, by multiple input and multiple output, makes full use of frequency diversity effect, while the mobile user, by single- point sending and multi- point receiving, makes full use of space diversity effect, thus to improve the communication rate of HF communication network. Meanwhile the system structure can also support flexible networking in accordance with the actual demand of emergency communication network, thus to further improve the reliability of HF communication network. |
