摘要：
One of the important means by which 5G can be implemented is by Ultra-Dense Multi-Tier future cellular network. We have studied the effect of the densification of network, Signal to Noise plus Interference ratio (SINR), network load, channel and channel bandwidth on the spectral efficiency and energy efficiency of this system. The importance of the spectral efficiency is also discussed. It is observed that as network load increases, spectral efficiency and energy efficiency decreases for given network bandwidth. which can be improved with the help of SINR or the densification of network. We have found out the exact higher modulation method M-Quadrature Amplitude Modulation (M-QAM) used for the given system and how it can be improved. By using higher M-QAM method, we can transmit more bits simultaneously. The spectral efficiency and energy efficiency of the system increases. It was found that as network bandwidth increases, spectral efficiency got decreases. We have also found the optimum value of bandwidth to maximize the spectral efficiency of this system.
