| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 106 === The proposed 5G Massive Antenna MDMA cellular system is an interference limited system [1], any excessive transmission power of data will aggravate the interference. In this thesis, we research on several power control algorithms and soft handoff methods in order to suppress the interference and improve the system capacity. The enhanced SIR power control algorithm is proposed to increase the system capacity and decrease the convergence rate of power control algorithm. Besides, the power ratio for soft handoff is adjusted to suppress both inter-cell and intra-cell interference. In addition, after soft handoff the modified SIR power control algorithm is used to further suppress the interference, so that we can achieve much better system capacity improvement.
