Massive MIMO-OFDM Channel Acquisition with Time-Frequency Phase-Shifted Pilots
Jinke Tang, Xiqi Gao, Li You +5
In this paper, we propose a channel acquisition approach with time-frequency phase-shifted pilots (TFPSPs) for massive multi-input multi-output orthogonal frequency division multip…
Simplified Information Geometry Approach for Massive MIMO-OFDM Channel Estimation -- Part II: Convergence Analysis
Jiyuan Yang, Yan Chen, Mingrui Fan +3
In Part II of this two-part paper, we prove the convergence of the simplified information geometry approach (SIGA) proposed in Part I. For a general Bayesian inference problem, we…
Group Information Geometry Approach for Ultra-Massive MIMO Signal Detection
Jiyuan Yang, Yan Chen, Xiqi Gao +2
We propose a group information geometry approach (GIGA) for ultra-massive multiple-input multiple-output (MIMO) signal detection. The signal detection task is framed as computing t…
An Information Geometry Interpretation for Approximate Message Passing
Bingyan Liu, An-An Lu, Mingrui Fan +2
In this paper, we propose an information geometry (IG) framework to solve the standard linear regression problem. The proposed framework is an extension of the one for computing th…
Efficient Information Geometry Approach for Massive MIMO-OFDM Channel Estimation
Jiyuan Yang, Yan Chen, Mingrui Fan +6
We investigate the channel estimation for massive multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. We revisit the information geometry…
