Abstract: A kind of parallel structure of the FIR filter is gotten by expressing the polynomial signal as the parallel form in this paper.By analyzing the parallel structure of FIR filter,several kinds of parallel processing algorithms of the adaptive FIR filter are presented.At the same time,the corresponding systolic implementation structures of these algorithms are given. -
