최소자승법을 이용한 Constrained Multichannel FIR 적응 빔 형성 알고리즘
Constrained Multichannel Adaptive FIR Beamforming Algorithm Based upon Least Squares Method
초록
In adaptive antenna, several models are known according to a prior knowledge about jammer signal. Among those, Frost model with contraint is generally used however it has the problem that convergence speed is slow and that stability is not good. To improve such problems, this paper proposes constrained NLMS algorithm using LS method. In addition, the result obtained by applying this algorithm to Duvall antenna model is compared with that of Frost model.
