Addressing the hadrware impairments on the communication performance. You can see many papers related to this. Some examples are power amplifier non-linearity, oscillator phase noise, phase shifter non linearity and beam squinting, mutual coupling in array antennas and beamforming.
Have you ever thought about what kind of antenna array can be formed if the clock synchronization of 100000 3m antenna satellite stations within 1000km is kept within 1ns. Supported frequencies, SNR?
