摘要
根据多参考输入自适应干扰抵消原理,提出基于方程误差结构的多参考输入自适应ⅡR干扰抵消器,给出具体算法并分析其性能。提出多部跳频电台同平台装载的自适应ⅡR同址干扰抵消方案,并对3种算法的性能进行仿真。仿真结果表明,多参考输入自适应ⅡR干扰抵消算法具有很好的收敛速度、收敛精度和稳定性,可以取得更好的跳频同址干扰抵消性能。
A novel multiple reference adaptive ⅡR interference cancellation algorithm based on the equation error structure and the implement scheme of adaptive cosite interference canceller with multiple FH radios is presented. The performance of multiple reference adaptive ⅡR algorithms, multiple reference LMS algorithm, and multiple reference RLS algorithm in FH eosite interference cancellation are compared. The simulation result shows that the performance of the new algorithm is much better than the other two ones and it has faster convergence speed, smaller steady state error, and better robustness in time variable system.
