CONTROLLABLE FILTER TO DIAGONALIZE A TRANSMISSION CHANNEL |
摘要 |
<p>The present invention relates to a node (1) in a wireless communication network, where the node (1) is arranged to receive at least two signals (y1(n), y2(n)) which correspond to at least two transmitted uncorrelated signal streams (x1(n), X2(n)) which have been transmitted to the node via a channel. The channel (2) is represented by means of a channel matrix (H(q-1)). The node (1) comprises a controllable filter structure (3) that is arranged to diagonalize the channel matrix (H(q-1)) such that a channel matrix estimation (H(q-1)) may be obtained. The present invention also relates to a corresponding method.</p> |
