Data-Aided Channel-Gain Calibration Algorithm for Recovering Channel Amplitude Reciprocity in SFLC-OFDM Systems

This paper proposes a practical gain calibration algorithm that estimates and compensates for channel amplitude asymmetry in a space-frequency line code (SFLC) orthogonal frequency division multiplexing (OFDM) system. During uplink (UL) communications from the base station (BS) to user equipment (UE...
