AI-based receiver boosts spectral efficiency in MIMO-OFDM systems

Researchers have developed a new framework for optimizing power allocation and designing AI-based receivers for superimposed data and reference symbol transmissions in MIMO-OFDM systems. The proposed AI-ICED receiver, utilizing Transformer encoders, aims to improve spectral efficiency by integrating channel estimation and detection iteratively. Simulation results indicate that this approach enhances spectral efficiency compared to traditional methods that use non-overlapped symbols. AI

IMPACT This research could lead to more efficient wireless communication systems by leveraging AI for signal processing.
