Efficient Channel Estimation for RIS-Aided MIMO Communications With Unitary Approximate Message Passing

Yabo Guo et al.

Summary: Reconfigurable intelligent surface (RIS) has great potential in wireless networks for achieving high energy efficiency, extended coverage, improved capacity, and massive connectivity. However, accurately acquiring channel state information for RIS-aided communications is challenging. Existing channel estimation methods for RIS-aided multiple-input and multiple-output (MIMO) communications have high computational complexity and special requirements on matrices involved, hindering their applications. In this work, a new signal model is derived and a more efficient channel estimator based on unitary approximate message passing (UAMP) is developed, which has linear complexity with the number of RIS units and does not have special requirements on matrices. Extensive numerical results show that the proposed estimator outperforms existing methods and reduces training overhead and latency.

Sheng Luo et al.

Summary: This paper investigates the uplink communication of a reconfigurable intelligent surface (RIS) assisted system, proposing Transmit SM (TSM) and Receive SM (RSM) schemes to enhance system reliability through optimization of power allocation and reflection coefficients.
