Hello,
We are implementing SVD Beamforming using CSI in 2x2 MIMO. However, there is one fatal problem. Even though the transceiver is in a fixed state, the CSI continues to fluctuate irregularly. The system configuration uses OFDM, and channel estimation is performed using a comb type pilot. Currently, CSI does not change during 20 OFDM symbols, but thereafter CSI changes. SVD Beamforming requires that the CSI does not change for a long time, which causes a fatal error in the current system. I would like to hear from professional engineers about this problem. Please help me.
Thank you.
