Application Research of Multi-antenna Technology in 5GHz Modulation System

Multi-antenna technology can improve the transmission rate and transmission quality of signals, and related research is also a hot spot in the current communication field. In this paper, the influence of multi-antenna communication system transmission is studied and discussed, and some conclusions are obtained through simulation. The simulation data results show that factors such as the number of transceiver antennas, modulation methods, and noise have a great impact on the signal modulation results. Compared with the traditional single-transmit and single-receive antenna mode, the multi-antenna system has better performance. Under the premise of the same noise ratio, the bit error rate of the multi-antenna communication system is lower.
