In the process of self-interference and self-adaptive cancellation,this paper proposes an improved keep-balance recursive least square(KB-RLS)algorithm based on the practical engineer-ing application requirements of high convergence accuracy,fast convergence speed and low algo-rithm complexity,and builts the corresponding hardware architecture,based on this architecture,performs simulation test by capturing the signals in the actual electromagnetic environment,and compares the cancellation results of the improved algorithm with that of the existing classical RLS algorithm.The results show that the algorithm can obtain better cancellation effect for complex e-lectromagnetic signals in the actual environment.
