Abstract
An equalizer for equalizing a composite signal originating from a given number of simultaneous data streams able to be received over a communication channel, on a given number of antennas, at one or more radio units, in a wireless communication system. The equalizer performs matrix operations when the number of receiving antennas associated with the composite signal is lower than the number of antennas supported by the equalizer. The channel matrix and the signal and interference covariance matrices are manipulated. The antenna dimension is increased, padding is then added and the transmitted signal vector is finally determined based on the altered matrices.A baseband processing unit, a method and a computer program are also claimed.
