Downlink output power requirements with an experimental-based indoor LOS/NLOS MIMO channel models at 10 GHz to provide 10 Gbit/s

The present paper studies link output power requirements per connection in order to provide 10 Gbit/s or more with included MIMO beam-specific path gains for spatially multiplexed data streams. Time-duplexing orthogonal frequency-division multiplexing 5G system is examined. System performance is considered in line-of-sight (LOS) and non-LOS channels. This work utilizes RF modelling method where digital signal processing is abstracted to minimum SNR requirement definitions and RF system SNR described based on transmitter and receiver performance related to output and input power levels. As the output of this work represents indoor link RF output power requirements, the results can be utilized in several research directions; e.g., providing dynamic range requirements for a power amplifier concept and for RF transceiver architecture optimization in terms of complexity and power consumption.
