Let a full-duplex multiuser MISO system use MIMO precoding with an increasing number of access-point transmit and receive antennas, and let the downlink signal-to-interference-plus…

Let $\mathbf{C}_{j}^{{\rm F}}$ denote the precoding matrix used by the $j$th small-cell network node for its backhaul signal $\mathbf{u}_{j,\mathrm{b}}[t]$. Unitary precoder conjec…
