【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。更多还原

【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.更多还原
