A Rate-Splitting Approach to Fading Channels With Imperfect Channel-State Information [PDF]
IEEE Transactions on Information Theory, 2014 As shown by Médard, the capacity of fading channels with imperfect channel-state information (CSI) can be lower-bounded by assuming a Gaussian channel input $X$ with power $P$ and by upper-bounding the conditional entropy $h(X|Y,\hat{H})$ by the entropy of a Gaussian random variable with variance equal to the linear minimum mean-square error in ...

Robust MMSE Precoding Strategy for Multiuser MIMO Relay Systems with Switched Relaying and Side Information [PDF]
, 2013 In this work, we propose a minimum mean squared error (MMSE) robust base station (BS) precoding strategy based on switched relaying (SR) processing and limited transmission of side information for interference suppression in the downlink of multiuser ...

Impact of Imperfect Channel State Information on RS Coding Aided Hybrid-ARQ in Rayleigh Fading Channels [PDF]
, 2010 Hybrid Automatic-Repeat-reQuest (ARQ) schemes are capable of maintaining reliable communications for transmission over hostile wireless channels. In coherent detection aided schemes, the achievable performance substantially depends on the accuracy of ...

Performance Analysis of Space-Time Block Codes in Flat Fading MIMO Channels with Offsets
EURASIP Journal on Wireless Communications and Networking, 2007 We consider the effect of imperfect carrier offset compensation on the performance of space-time block codes. The symbol error rate (SER) for orthogonal space-time block code (OSTBC) is derived here by taking into account the carrier offset and the ...

Robust Precoding for Multi-User Visible Light Communications with Quantized Channel Information
Sensors, 2022 In this paper, we address the design of multi-user multiple-input single-output (MU-MISO) precoders for indoor visible light communication (VLC) systems. The goal is to minimize the transmitted optical power per light emitting diode (LED) under imperfect

Communication rates for fading channels with imperfect channel-state information
, 2023 The present thesis studies information rates for reliable transmission of information over fading channels in the realistic situation where the receiver has only imperfect channel-state knowledge. Of particular interest are analytical expressions of achievable transmission rates under imperfect and no CSI, that is, lower bounds on the mutual ...

Low-Complexity ZF/MMSE MIMO-OTFS Receivers for High-Speed Vehicular Communication
IEEE Open Journal of the Communications Society, 2022 Orthogonal time-frequency space (OTFS) scheme, which transforms a time and frequency selective channel into an almost non-selective channel in the delay-Doppler domain, establishes reliable wireless communication for high-speed moving devices.
