Robust generalized sidelobe canceller based on eigenanalysis and a MaxSINR beamformer Research Articles

Quan-dong WANG, Liang-hao GUO, Wei-yu ZHANG, Sui-ling REN, Chao YAN

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 7,   Pages 975-987 doi: 10.1631/FITEE.1700367

Abstract: To estimate the interference-plus-noise (IPN) statistics characteristics, conventional signal of interest(SOI) extraction methods usually collect a large number of segments where only the IPN signal is activeThe blocking matrix is obtained by incorporating the effective reconstruction into the maximum signal-to-interferenceplus-noiseratio (MaxSINR) beamformer.It can minimize the influence of signal leakage and maximize the IPN power for further noise and interference
