1. A method comprising:
generating a vector from a covariance matrix of a received signal;
inputting the vector to a neural network to obtain an enhanced vector;
converting the enhanced vector into an enhanced matrix; and
performing interference whitening on the received signal using a whitening filter based on the enhanced matrix.
