Title:
APPARATUS, METHOD AND COMPUTER PROGRAM FOR AN INTERFERENCE-AWARE RECEIVER
Document Type and Number:
WIPO Patent Application WO/2017/093740
Kind Code:
A3
Abstract:
Apparatus, methods, and computer programs for an interference-aware receiver are disclosed. The apparatus comprises: a multi-antenna array comprising a plurality of antennas; a covariance matrix estimator configured to obtain an estimated covariance matrix based on known pilot symbols and a plurality of antenna signals received by the multi-antenna array; a covariance matrix adapter configured to determine a value of a scenario-independent metric based on the estimated covariance matrix, compare the determined value to a target value of the metric for a current configuration of the signal receiving apparatus, and determine an adapted covariance matrix based on the result of the comparison; and a signal processing unit configured to perform further signal processing using the adapted covariance matrix. In some embodiments, the metric is a likelihood ratio and the target value is the median value of a probability distribution function associated with the current receiver configuration.
