| Abstract: | Aimed at the adaptive interference cancellation system for improving the transmitter-receiver isolation of the jammer, a fast LMS adaptive algorithm in frequency domain is realized by using fast FFT technology, the algorithm is a replacement of LMS algorithm in time domain. The analysis indicates that the convergence of the algorithm is approximate with LMS algorithm in time domain, moreover it have less computation, which are propitious to realize cancellation system in real time, the computer simulation confirms the correctness of the analysis and the feasibility of the algorithm. |
