On Spherical Linear Interpolation for MIMO-OFDM Beamforming Systems
We analyze linear channel estimation for MIMO-OFDM systems and propose a spherical linear interpolator in closed-form for the beamforming codewords. We also suggest a hybrid interpolator using a simplified version of the derived interpolator. Simulation results show that the proposed schemes are efficient and competitive with respect to the feedback overhead and have low complexity.
