On the effect of shadowing correlation and pilot assignment on hybrid precoding performance for cell-free mmWave massive MIMO UDN system
One of promising transmission technologies for beyond-5G wireless communication is cell-free massive MIMO where all the access nodes (ANs) cooperate to coherently serve all the user equipments (UEs). Based on the benefits from massive MIMO, the novel notion of cell-free network architecture is adequ...
