Applied Sciences, 2023 In this paper, we consider a coded cooperative communication network with multiple energy-harvesting (EH) relays. In order to adequately address the problem of error propagation due to the erroneous decoding at the relays, as in the case of conventional ...

Bilayer Protograph Codes for Half-Duplex Relay Channels [PDF]
, 2013 Despite encouraging advances in the design of relay codes, several important challenges remain. Many of the existing LDPC relay codes are tightly optimized for fixed channel conditions and not easily adapted without extensive re-optimization of the code.

On the Reliability Function of the Discrete Memoryless Relay Channel [PDF]
IEEE Transactions on Information Theory, 2013 Bounds on the reliability function for the discrete memoryless relay channel are derived using the method of types. Two achievable error exponents are derived based on partial decode-forward and compress-forward, which are well-known superposition block ...

On the Gaussian Half-Duplex Relay Channel [PDF]
IEEE Transactions on Information Theory, 2013 This paper considers the Gaussian half-duplex relay channel (G-HD-RC): a channel model where a source transmits a message to a destination with the help of a relay that cannot transmit and receive at the same time.

Full-Duplex Relay with Delayed CSI Elevates the SDoF of the MIMO X Channel
Entropy, 2021 In this article, the sum secure degrees-of-freedom (SDoF) of the multiple-input multiple-output (MIMO) X channel with confidential messages (XCCM) and arbitrary antenna configurations is studied, where there is no channel state information (CSI) at two ...

Lower bounds on the estimation performance in low complexity quantize-and-forward cooperative systems [PDF]
, 2015 Cooperative communication can effectively mitigate the effects of multipath propagation fading by using relay channels to provide spatial diversity. A relaying scheme suitable for half-duplex devices is the quantize-and-forward (QF) protocol, in which ...

Memoryless relay strategies for two-way relay channels [PDF]
IEEE Transactions on Communications, 2009 We propose relaying strategies for uncoded two-way relay channels, where two terminals transmit simultaneously to each other with the help of a relay. In particular, we consider a memoryless system, where the signal transmitted by the relay is obtained by applying an instantaneous relay function to the previously received signal.

An iterative noncoherent relay receiver for the two-way relay channel [PDF]
2013 IEEE International Conference on Communications (ICC), 2013 Digital network coding improves the throughput of the two-way relay channel by allowing multiple sources to transmit simultaneously to the relay. This work considers the development of a relay receiver applying a specific modulation and channel coding ...

Visual Recovery Reflects Cortical MeCP2 Sensitivity in Rett Syndrome
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Rett syndrome (RTT) is a devastating neurodevelopmental disorder with developmental regression affecting motor, sensory, and cognitive functions. Sensory disruptions contribute to the complex behavioral and cognitive difficulties and represent an important target for therapeutic interventions.
