Near-Field MMSE Channel Estimation for THz RIS-aided Communications with Electromagnetic Interference
Wen-Xuan Long, Marco Moretti, Giacomo Bacci +1
This letter investigates the channel estimation problem in THz wireless communications where a RIS is employed to assist wireless transmission between different devices. Unlike exi…
