| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 106 === For the 5G cellular system, we proposed a massive antenna multipath division multiple access (MDMA) system which is interference-limited. The system capacity and BER performance are both affected by interference from other users. In this thesis, we focus on the discussion of downlink control signal detection with interference from other users. We use DPSK spread spectrum modulation to transmit control data. For the purpose of reducing interference we use spread spectrum technology to improve the performance of control signal BER. We propose different methods to detect path and compare different path selection methods. Finally, we evaluate the control data detection performance through computer simulation.
