摘要
摘要:战术指挥车内多部电台同时工作，发射电台将对接收电台产生严重的互扰。针对上述问题，该文提出基于多通道最小均方算法(MCLMS)的多发单收同车电台射频干扰对消方法。首先，分析同车电台N 发M 收情况可分离为M个N发单收场景的叠加，进而建立多发单收射频干扰对消模型。在此基础上，提出基于MCLMS算法的射频干扰对消方法，并理论分析该对消方法的性能，推导得出互扰对消比(MICR)与发射电台数目N、收敛因子
\begin{document}$\mu $\end{document}之间的闭合数学表达式。最后，通过仿真验证了理论结果的正确性，表明该方法能够有效抑制同车发射电台对接收电台的互扰影响，增强指挥车电磁兼容性。

Abstract:The transmit radios would severely interfere the receive radios, only if they are simultaneously operating in the same tactical command vehicle. Considering this problem, the RF interference cancellation method for multi-transmits and single-receive co-vehicle radios, based on Multi-Channel Least Mean Square (MCLMS) algorithm, is proposed. Firstly, the analysis indicates that the situation of N-transmits and M-receives co-vehicle radios is the equivalent of M case of N-transmits and single-receive, by which the RF interference cancellation model of multi-transmits and single-receive is constructed. Secondly, the RF interference cancellation method based on MCLMS algorithm is presented, and the performance of this method is analyzed to obtain the mathematical relation expression between Mutual-Interference Cancellation Ratio (MICR) and transmit radio number N, convergence factor
\begin{document}$\mu $\end{document}. Finally, the simulations demonstrate the validity of the theory result, and indicate that the mutual-interference between transmit radios and receive radios is efficiently suppressed to enhance the electromagnetic compatibility of communication command vehicle.
