A research of an adaptation algorithm convergence using spatial signal pre-processing
2016 5th Mediterranean Conference on Embedded Computing (MECO)(2016)
Abstract
The paper investigates a problem of increasing convergence rate for the process of adaptive weight vector adjustment in spatially reconfigurable antenna systems on the background of point-source interferences. It is shown that pre-processing with adjustment of adaptive antenna array element spacing gives the capability to reduce considerably eigenvalues spread of spatial correlation matrix and to obtain faster convergence of gradient adaptation algorithm.
