Abstract EN
The concept of close-loop beamforming for MIMO system was well known proposed the singular value decomposition on channel matrix.
This technique can improve the capacity performance, but the cost of feedback channel and the complexity processing discard the interest of implementation.
Therefore, this paper aims to investigate the benefit of using an open-loop beamforming for MIMO system in practical approaches.
The low-profile concept of open-loop beamforming which is convenient for implementation is proposed by just inserting Butler matrices at both transmitter and receiver.
The simulation and measurement results indicate that the open-loop beamforming with Butler matrix outperforms the conventional MIMO system.
Although, the close-loop beamforming offers a better performance than open-loop beamforming technique, the proposed system is attractive because it is low cost, uncomplicated, and easy to implement.
