Abstract: The forward-precoding scheme could significantly reduce downlink fronthaul traffic in cell-free mobile networks by compressing resource-block (RB)-granularity precoding matrices.

Symbol-level precoding represents a class of advanced signal-processing methods that exploit knowledge of instantaneous user data symbols and channel state information at the transmitter to shape ...

Precoding is a signal processing technique that modifies the phases and amplitudes of wireless signals to combat channel distortion and optimize the quality and reliability of data transmissions. It ...

Abstract: Hybrid digital-analog precoding is essential for balancing communication performance, energy efficiency, and hardware costs in millimeter wave (mmWave) massive multiple-input multiple-output ...
