Scheduling to Minimize Age of Incorrect Information with Imperfect Channel State Information [PDF]
Entropy, 2021 In this paper, we study a slotted-time system where a base station needs to update multiple users at the same time. Due to the limited resources, only part of the users can be updated in each time slot.

Impacts of Imperfect Channel State Information, Transceiver Hardware, and Self-Interference Cancellation on the Performance of Full-Duplex MIMO Relay System [PDF]
Sensors, 2020 Imperfect channel state information (I-CSI) and imperfect transceiver hardware often happen in wireless communication systems due to the time-varying and random characteristics of both wireless channels and hardware components.

Secure Broadcasting With Imperfect Channel State Information at the Transmitter [PDF]
IEEE Transactions on Wireless Communications, 2016 We investigate the problem of secure broadcasting over fast fading channels with imperfect main channel state information (CSI) at the transmitter. In particular, we analyze the effect of the noisy estimation of the main CSI on the throughput of a broadcast channel where the transmission is intended for multiple legitimate receivers in the presence of ...

Resource Allocation in OFDMA Networks With Imperfect Channel State Information
IEEE Communications Letters, 2014 This letter investigates the effect of imperfect channel state information (CSI) on the performance of radio resource management for a downlink multi-user OFDMA system. It is shown that the imperfect CSI introduces a signal-and-power dependent noise term, which makes the symbol error rate (SER) constellation-point dependent, and yields an error floor ...

The DoF region of two‐user MIMO broadcast channel with delayed imperfect‐quality CSIT
Electronics Letters, 2022 The channel state information at the transmitter (CSIT) play an important role in the performance of wireless networks. The CSIT model can be delayed and imperfect‐quality, since the feedback link has a delay and the channel state information (CSI ...

Robust Tensor Decomposition for Heterogeneous Beamforming Under Imperfect Channel State Information
IEEE Open Journal of Signal Processing, 2023 We propose a new robust variation of the tensor decomposition known as the multi-linear generalized singular value decomposition (ML-GSVD), and demonstrate its effectiveness in the design of joint transmit (TX) and receive (RX) beamforming (BF) for both ...
