英文摘要：

The linearly constrained minimum variance （LCMV） algorithm based on the power inversion array and its iterative formula are deduced in the paper, which avoids the complexities of matrix inversion. The simulation model is constructed in MATLAB to simulate the actual environment of interference and signal sources, and the signals received by the antenna array are also reconstructed. The simulation is performed for the uniform linear array and the circular array, and the antenna array pattern is obtained during this process. These create good conditions for making useful adaptive antenna design. The results obtained demonstrate that the scheme of LCMV based on the power inversion array holds for the case that the strong interference exists, with high convergent speed and easy realization. The stronger the interferences are, the deeper nulls it will give.
