A New Millimeter Wave MIMO System for 5G Networks. (arXiv:1807.04851v1 [cs.IT])
来源于:arXiv
Millimeter Wave (mmWave) band provides a large spectrum to meet the
high-demand capacity by the 5th generation (5G) wireless networks. However, to
fully exploit the available spectrum, obstacles such as high path loss, channel
sparsity, and hardware complexity should be overcome. To this end, the present
paper aims to design a new multiple-input multiple-output (MIMO) system using
lens-based multi-beam reconfigurable antennas. The proposed MIMO system uses
complete lens at the transmitter and incomplete lens at the receiver. To reduce
hardware complexity, we utilize an optimal beam selection technique. Our
analysis demonstrates that the proposed MIMO system along with the optimal beam
selection technique increases the average signal-to-noise ratio (SNR). Also,
simulations show that the system achieves full-diversity gain. 查看全文>>
