Abstract:
The disclosure relates to a radio receiver, comprising: a receiving stage configured to receive a multi-layered signal comprising a plurality of layers; a division stage configured to divide the plurality of layers into a first subset and a second subset (206); a first whitening filter configured to filter the multi-layered signal based on a noise and interference covariance measure derived from the second subset to provide a first filtered multi-layered signal; and a first detection stage configured to detect at least one layer of the first subset based on the first filtered multi-layered signal.

Claim (Index 43):
The radio receiver of  claim 42 ,\n wherein the whitening filter W is configured to derive the noise and interference covariance matrix RNI according to the following relations: y = H \ue8a0 [ P 1 \ue89e P 2 ] \ue8a0 [ s 1 s 2 ] + H \ue8a0 [ P 3 \ue89e P 4 ] \ue8a0 [ s 3 s 4 ] + n ; R N = \u03c3 2 \ue89e I R NI = H \ue8a0 [ P 3 \ue89e P 4 ] \ue8a0 [ P 3 \ue89e P 4 ] H \ue89e H H + R N or R NI = \ue89e E \ue89e { yy H } - H \ue8a0 [ P 1 \ue89e P 2 ] \ue8a0 [ P 1 \ue89e P 2 ] H \ue89e H H = \ue89e R yy - H \ue89e \ue89e P 1 \ue89e P 1 H \ue89e H H - HP 2 \ue89e P 2 H \ue89e H H with R NI = W - 1 \ue89e W - H , where y is the four-layered signal, s 1  is the first layer, s 2  is the second layer, s 3  is the third layer and s 4  is the fourth layer of the four-layered signal, P 1  is a precoding matrix of the first layer, P 2  is a precoding matrix of the second layer, P 3  is a precoding matrix of the third layer and P 4  is a precoding matrix of the fourth layer, H is a channel matrix and R N  is a noise matrix.
