Short-Term BF Research on TD-LTE System

The beamforming used in TD-LTE systems is a somewhat more complex proposition. Eigenvalue-based beamforming (EBB) is based on Singular value decomposition. It's included short-term BF and Long-term BF two methods and applied in different channel knowledge. In this paper, firstly, it described short-term BF algorithm, especially focused on the method how to apply for OFDM and TD-LTE system. And then make a SW designing implementation for short-term BF, too. It is involved in some basic idea of implementation, SRS combiner and MAC layer designing. Finally, the paper gives the detailed simulation for different performance index and gets some technical conclusion.
