| 摘 要： | 在相干干扰的条件下，推导了MMSE，LCMV两种波束形成器的输出信号情况。理论推导证明了基于MMSE准则的波束形成器，具有良好的输出信干噪比(SINR)，而基于LCMV准则的波束形成器输出信号完全被湮没于噪声干扰中的原理。仿真结果进一步显示了这种分析推导的正确性。

| Abstract: | in the condition of coherent signals (interferences) presence,the performances of beamformer based on the MMSE and LCMV principle respectively were deduced in theory.It was proofed that the MMSE beamformer had a good performance in outputting SINR;moreover the outputting signal of LCMV beamformer was submerged in noise and interferences.Numerical simulations demonstrate that the analysis of performance is valid and true. |
