Abstract: In aspect, the disclosure includes a method of configuring a MIMO wideband receiver. The method would include estimating, on a SISO basis, a set of post-processing parameters for a plurality of receiver channels; receiving, by each of the plurality of receiver channels, a first test signal which is transmitted from a first transmitter channel on a MIMO basis; calculating a first set of crosstalk parameters in response to receiving the first test signal; receiving, by each of the plurality of receiver channels, a second test signal which is transmitted from a second transmitter channel on the MIMO basis; calculating a second set of crosstalk parameters in response to receiving second test signal; and calculating the set of post-processing parameters based on the first set of crosstalk parameters and the second set of crosstalk parameters by cancelling a crosstalk interference among plurality of receiver channels.
