Irregular repetition slotted ALOHA over the Rayleigh block fading channel with capture [PDF]

open access: yes2017 IEEE International Conference on Communications (ICC), 2017
Random access protocols relying on the transmission of packet replicas in multiple slots and exploiting interference cancellation at the receiver have been shown to achieve performance competitive with that of orthogonal schemes.

Covert Wireless Communications With Channel Inversion Power Control in Rayleigh Fading [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2018
In this work, we adopt channel inversion power control (CIPC) to achieve covert communications aided by a full-duplex receiver. Specifically, the transmitter varies the power and phase of transmitted signals as per the channel to the receiver, such that ...

Outage Probability of Energy Harvesting Relay-Aided Cooperative Networks Over Rayleigh Fading Channel [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2014
Energy harvesting technique is a potential way for relay node energy supply in cooperative networks with respect to deployment flexibility and maintenance charge reduction. However, unlike traditional power source, it is intuitive that the fluctuation of

MLSE receiver for the dispersive Rayleigh fading channel [PDF]

open access: yesProceedings of ICC'97 - International Conference on Communications, 2002
A maximum likelihood sequence estimator for the dispersive Rayleigh fading channel is developed. Following [1, 2], the MLSE uses a Kalman based channel estimator to acquire the channel parameters necessary to formulate the maximum likelihood metric. However, unlike the MLSE receiver presented in [1, 2], the proposed receiver uses the f-power series ...

Adaptive modulation in a slow Rayleigh fading channel [PDF]

open access: yesProceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002
A novel, uneven protection phase shift keying technique is proposed for the encoding of the required modulation scheme in an adaptive modem arrangement, which exhibits an improved performance in comparison to previously proposed schemes. The performance is derived numerically and a system dependent optimisation is presented.

The Slashed‐Rayleigh Fading Channel Distribution

open access: yesMathematical Problems in Engineering, 2019
We propose an alternative distribution for modelling fading‐shadowing wireless channels. This distribution presents certain advantages over the Rayleigh‐lognormal distribution and the K distribution and has proved useful in the setting described. We obtain closed‐form expressions for the average channel capacity and for the average bit error rate of ...

The Rayleigh Fading Channel Prediction via Deep Learning

open access: yesWireless Communications and Mobile Computing, 2018
This paper presents a multi-time channel prediction system based on backpropagation (BP) neural network with multi-hidden layers, which can predict channel information effectively and benefit for massive MIMO performance, power control, and artificial ...

Rayleigh Fading Multi-Antenna Channels [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
Summary: Information theoretic properties of flat fading channels with multiple antennas are investigated. Perfect channel knowledge at the receiver is assumed. Expressions for maximum information rates and outage probabilities are derived. The advantages of transmitter channel knowledge are determined and a critical threshold is found beyond which ...

Covert Communications With a Full-Duplex Receiver in Non-Coherent Rayleigh Fading

open access: yesIEEE Transactions on Communications, 2021
In a majority of research on covert communications, knowledge about channel state information (CSI) of main channel and/or warden channel is assumed to be known or partially known.
