Rayleigh Fading Multi-Antenna Channels [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
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.

Nearest Neighbor Decoding and Pilot-Aided Channel Estimation for Fading Channels [PDF]

open access: yesEntropy, 2020
We study the information rates of noncoherent, stationary, Gaussian, and multiple-input multiple-output (MIMO) flat-fading channels that are achievable with nearest neighbor decoding and pilot-aided channel estimation.

An overview and analysis of BER for three diversity techniques in wireless communication systems [PDF]

open access: yesYugoslav Journal of Operations Research, 2015
Characteristics of a wireless communication channel are subjected to a large scale deterioration process, referred to as the problem of fading. This paper discusses different techniques for mitigating the fading problems.

Federated Learning Over Wireless Fading Channels [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2020
We study federated machine learning at the wireless network edge, where limited power wireless devices, each with its own dataset, build a joint model with the help of a remote parameter server (PS). We consider a bandwidth-limited fading multiple access channel (MAC) from the wireless devices to the PS, and propose various techniques to implement ...

On the K and KG fading channels [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2009
In this paper, the composite Rayleigh-Gamma and Nakagami-Gamma distributions are considered. Multipath short-term fading and long-term fading (shadowing) affect wireless channels.

Statistical Characteristics Test of Nakagami Fading Channel Based on CvM Algorithm [PDF]

open access: yesJisuanji gongcheng, 2022
The Nakagami fading channel model can simulate different channel fading environments using different values of fading factor m, and the simulation data are in good agreement with the actual measured values, which are widely used in the field of channel ...

Polar coding for fading channels [PDF]

open access: yes2013 IEEE Information Theory Workshop (ITW), 2013
A polar coding scheme for fading channels is proposed in this paper. More specifically, the focus is Gaussian fading channel with a BPSK modulation technique, where the equivalent channel could be modeled as a binary symmetric channel with varying cross-over probabilities.

The Flexibility of the Generalized Gamma Distribution in Modeling the Fading Based on Kullback-Leibler and Kolmogorov-Smirnov Criteria

open access: yesIEEE Access, 2020
The precision of Rayleigh distribution, as the simplest fading model in Non-Line-of-Sight (NLOS) channels, is low in high-resolution radars and long-distance communication receivers.

Secure Communication Over Fading Channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2008
The fading broadcast channel with confidential messages (BCC) is investigated, where a source node has common information for two receivers (receivers 1 and 2), and has confidential information intended only for receiver 1. The confidential information needs to be kept as secret as possible from receiver 2. The broadcast channel from the source node to

Upper Capacity Bounds of MIMO Wireless Systems Through Fading Channels

open access: yesAdvances in Electrical and Electronic Engineering, 2015
This paper investigates the upper capacity bounds of MIMO systems with correlation and antenna selection techniques in general fading environments. With Antenna Selection techniques, the increased hardware complexity due to multiple antennas and large ...
