Abstract
Beam forming has been greatly applied in TD-SCDMA, but in the 3G long-term evolution (LTE), multi-antenna solution aims to use multi-input-multi-output (MIMO). Usually MIMO requires enough large antenna space to ensure uncorrelated multi-channels, whereas beam forming antennas need small antenna space. But this years’ research has shown the combination feasibility of beam forming and MIMO. In this paper, the 3GPP special channel model (SCM) has been researched and the beam forming is added to the LTE. Because of the beam forming combination, the number of transmitted antennas can not be restricted by 3GPP specification about LTE. Simulation results validate the efficiency. This gives a smooth evolution path from TD-SCDMA to LTE, and the advantage of beam forming can be inherited.
