As known, this band is suffering from high path loss, high penetration loss, and other problems. Recently, hybrid antenna array has been proposed to alleviate these problems. This thesis aims to develop throughput enhancement techniques with hybrid antenna arrays. First, we propose a beamforming method taking multiple transmission paths (instead of one) into considerations. This method can reduce the performance loss due to erroneous beam-matching. Then, we propose an L-shaped antenna array and develop a simple yet effective two-dimensional localization scheme, which is extended to three-dimensional. Finally, we propose a scheduling scheme that can conduct parallel transmission to maximize system capacity in multiple user environments. Simulations show that the proposed methods can greatly enhance the throughput of 60GHz OFDM networks. Wu, Wen-Rong 吳文榕 2014 學位論文 ; thesis 62 zh-TW |
