WebTheorem 1: The optimal values of the source beamforming vector, the destination combining vector, and the relay weight- ing matrix for the problem in (4) are given by: s⋆=b1, r⋆=f1, W⋆=σg1a1H, where we have used the SVD equations in (3), and σ= 1+P1φ2 1 −1 2. Note that W⋆is a rank one matrix. Proof: The optimization is accomplished in two steps.

Grassmannian Beamforming on Correlated MIMO Channels

WebEnter the email address you signed up with and we'll email you a reset link. WebMay 22, 2011 · Grassmannian beamforming is an efficient way to quantize channel state information in multiple-input multiple-output wireless systems. Unfortunately, multiuser systems require larger codebooks since the quantization error creates residual interference that limits the sum rate performance.
