Firstly, the performance of shared antenna system including TD- LTE (D band) and TD- SCDMA (F, A band) was theoreticaly analyzed, besides this, a system simulation aiming at the performance change of control channel (without beamforming) and traffic channel caused by sharing antenna is made. Subsequently the antenna pattern aiming at TD- LTE indoor distribution system is analyzed, finaly a discussion for the project implementation of TD- LTE antenna system are discussed.
