摘要
Due to reduce the calculation of distributed LCMV beamforming in fully connected WSN, a Householder Multistage Wiener Filter (HMSWF) based method for distributed LCMV beamforming is proposed. The new method effectively introduces HMSWF technology to avoid the local covariance matrix estimation and inversion. Consequently it can get the same output performance as distributed LCMV beamforming with less amount of calculation. In addition, the new method can be truncated in the recursive processing to further reduce the amount of calculation. Computational simulation results show that the new method achieves an excellent performance. ©, 2015, Chinese Institute of Electronics. All right reserved.
