Bouacha, ABendimerad, Ft2013-06-182013-06-182012https://dspace.univ-tlemcen.dz/handle/112/2408The multistage LSCMA beamforming algorithm is capable of detecting multiple input signals sources without pilot or training signals. it is comprised of acascade of LSCM array subsections, eash of which captures one of the signals impinging on the array. An adaptative signal canceller folows each LSCM array to remove captured signal from the input before processing by subsequent section. We also propose in this paper new method for blind algorithm initialization. The SMI is used to estimate initial weights of the LSCMA for a few samples.enSmart antennabeamforming algorithmconstant modulus algorithm (CMA)direct matrix inversion (DMI)normalized constant modulus algorithm (NCMA)Article
