摘要: 提出了一种新体制跳频网台盲分选方法，针对跳频通信异步非正交组网方式，将基于最大信噪比算法的盲源分离技术应用于跳频网台分选。建立了跳频网台盲分选仿真数学模型并进行了多跳频网台分选仿真。仿真结果验证了盲源分离技术应用在跳频网台分选中的可行性和有效性，得出了跳频网台盲分选方法对异步非正交组网方式的分选性能。Abstract: A new method for frequency hopping (FH) blind signal sorting is proposed based on the character and insufficiency of traditional method for FH separation of network. For the FH asynchronous nonorthogonal netting, the technology of BSS based on the maximum signal noise ratio algorithm is applied to signal sorting. The model of FH blind separation of network is established and a simulation test of signal sorting for multiple FH networks is carried out. Simulation results validate the feasibility of the method and the performance of the blind separation of network for FH asynchronous nonorthogonal netting is given.
