RF system requirement analysis and simulation methods towards 5G radios using massive MIMO
Methods of performing RF system requirement analysis towards 5th generation massive multiple input multiple output system are described. For the system analysis, digital signal processing is abstracted to minimum SNR requirement definitions and RF system SNR is described based on realistic but highly simplified transmitter and receiver performance related to output and input power levels, respectively. In addition, a simple link adaptation model is created for dynamic simulation tasks. As the contribution of antenna array is seen to become necessity in cm and mm wave bands for 5G systems, we show ways to include antenna modelling in system analysis. By using these analysis methods, we have generated a link level simulator that can be used for system analysis using different abstractions of antennas. Finally, it is shown that even simple RF models need to have certain implementation related details in order to provide good accuracy in link budget and operation range analysis.
