Operating Techniques Incomplete Keyword You can enter incomplete keywords on the device. In the current view, you do not need to enter complete keywords if the entered characters can match a unique keyword. This function improves operating efficiency. For example, to execute the display current-conf...

The related multiple-input multiple-output (MIMO) principle has been investigated [6,7,8]. Usually, multiple access techniques include orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA). OMA is widely used and analyzed, such as for time division multiple access (TDMA), ...
techniques WiFi or WiMAX . In large-scale wireless network, the WMN is implemented by integration of WiFi and WiMAX technologies (Bruno et al., 2005). The WMN structure comprises multiple APs which are connected to the wired internet backbone, a group of wireless mesh routers that provide ...
In the second case study, energy-efficient NOMA along with energy-harvesting techniques are analyzed, to understand the feasibility of NOMA as an energy-efficient transmission protocol for a multiple access cooperative network. Finally, in our third case study, we include a special case, where the...
