Application of Compressive Projection Principal Component Analysis to MIMO Channel Feedback Scheme
Chenhao Qi, Lenan Wu · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2010
In this letter, we apply recently proposed compressive projection principal component analysis (CPPCA) for MIMO channel feedback. A novel scheme with compressed feedback and efficient reconstruction is presented. Simulation results based on 3GPP spatial channel model (SCM) demonstrate the scheme is beneficial for large-scale MIMO systems.
