Abstract: Orthogonal space-time block-coded (OSTBC) orthogonal frequency-division multiplexing (OFDM) links for frequency-selective multiple-input multiple-output (MIMO ... precoding only needs the ...

Orthogonal frequency-division multiplexing has become the standard modulation format for 5G New Radio ... Figure 5 shows a basic block diagram of a complete end-to-end OFDM system consisting of a ...

In this paper, we consider a practical massive MIMO maritime BS with hybrid digital and analog precoding. Only the large-scale channel state information at the transmitter (CSIT) is considered so as ...
