REGULARIZED INTERFERENCE-PLUS-NOISE COVARIANCE MATRIX ESTIMATION

Abstract: apparatuses and methods in a communication system are disclosed. a signal is received. the signal comprises demodulation reference information. the apparatus compute estimates of the channel and of interference-plus-noise vectors. the interference-plus-noise vectors are used as input for choosing a tapering matrix and for determining shrinkage target matrix and parameter. an interference plus noise covariance matrix estimator is computed and used in an equalizer, which has as input an estimate of the interference-plus-noise covariance matrix.
