Summary

• What is new: A new algorithm for joint estimation of angle of arrival (AoA) and angle of departure (AoD) using received signal strength (RSS) in mmWave communications.
• Why this is important: The need for efficient indoor positioning in the mmWave spectrum for 5G services.
• What the research proposes: Proposing an algorithm that uses codebook-based beampatterns and a multi-antenna array to accurately estimate AoA and AoD from RSS.
• Results: Successful demonstration of improved indoor positioning overcoming LoS limitations, validated through real-time signal processing and a ray-tracing approach.
