Implementation Of A Non-Codebook Based Mu-Mimo System For Tdd Lte-Advanced

This paper presents a non-codebook based Multiple User Multiple Input Multiple Output (MU-MIMO) test-bed system for Time Division Duplexing (TDD) Long Term Evolution-Advanced (LTE-A), which has been implemented for verifying the performance of a dynamic precoding procedure. Using the parameter of propagation path gain, the proposed MU-MIMO system can adaptively switch the precoder to guarantee that the upper bound BER is maintained with a minimum computational burden.
