This paper characterizes the impacts of channel estimation errors and Rician factors on achievable data rate and investigates the user scheduling strategy, combining scheme, power…
BEM-Assisted Low-Complexity Channel Estimation for AFDM Systems over Doubly Selective Channels
Limin Liu, Zhe Li, Qihao Peng +3
In this paper, we propose a low-complexity channel estimation scheme of affine frequency division multiplexing (AFDM) based on generalized complex exponential basis expansion model…
Latency-Aware Resource Allocation for Integrated Communications, Computation, and Sensing in Cell-Free mMIMO Systems
Qihao Peng, Qu Luo, Zheng Chu +5
In this paper, we investigate a cell-free massive multiple-input and multiple-output (MIMO)-enabled integration communication, computation, and sensing (ICCS) system, aiming to min…
Performance Analysis of BEM-based Channel Estimation for OTFS with Hardware Impairments
Haowei Wu, Huanyu Chen, Qihao Peng +2
This letter studies the low-complexity channel estimation for orthogonal time frequency space (OTFS) in the presence of hardware impairments. Firstly, to tackle the computational c…
