| 摘要 | The research described in this paper shows how by combining CoMP with adaptable semi-smart antennas it is possible to improve the throughput of an OFDMA LTE system and at the same time reduce the power required for transmission; i.e. providing better performance at lower cost. Optimisation of antenna patterns is performed by a Genetic Algorithm to satisfy an objective function that considers throughput, number of UEs handled as well as power in the transmission. It is shown that the dominant effect is using the semi-smart antennas and that the results are not sensitive to small amounts of movement. |
