Dynamic Channel Knowledge Map Construction in MIMO-OFDM Systems
Wenjun Jiang, Xiaojun Yuan, Chenchen Liu +1
Channel knowledge map (CKM) is a promising paradigm for environment-aware communications by establishing a deterministic mapping between physical locations and channel parameters.…
Channel Estimation in Massive MIMO Systems with Orthogonal Delay-Doppler Division Multiplexing
Dezhi Wang, Chongwen Huang, Xiaojun Yuan +6
Orthogonal delay-Doppler division multiplexing~(ODDM) modulation has recently been regarded as a promising technology to provide reliable communications in high-mobility situations…
Near-Field Multiuser Localization Based on Extremely Large Antenna Array with Limited RF Chains
Boyu Teng, Xiaojun Yuan, Rui Wang +1
Extremely large antenna array (ELAA) not only effectively enhances system communication performance but also improves the sensing capabilities of communication systems, making it o…
Array Partitioning Based Near-Field Attitude and Location Estimation
Mingchen Zhang, Xiaojun Yuan, Boyu Teng +1
This paper studies a passive source localization system, where a single base station (BS) is employed to estimate the positions and attitudes of multiple mobile stations (MSs). The…
