Unveiling the Hyper-Rayleigh Regime of the Fluctuating Two-Ray Fading Model
IEEE Access, 2019 The recently proposed fluctuating two-ray (FTR) model is gaining momentum as a reference fading model in scenarios where two dominant specular waves are present.

Signal-to-Noise Ratio Comparison of Amplify-Forward and Direct Link in Wireless Sensor Networks [PDF]
, 2007 We compare the signal-to-noise ratio performances of an amplify-forward relay link and a direct link in a wireless sensor network. For a slow Rayleigh fading channel, an exact expression for the probability that the SNR of an amplify-forward relay link ...

Modeling Cellular Networks in Fading Environments with Dominant Specular Components [PDF]
, 2016 Stochastic geometry (SG) has been widely accepted as a fundamental tool for modeling and analyzing cellular networks. However, the fading models used with SG analysis are mainly confined to the simplistic Rayleigh fading, which is extended to the ...

On multilevel coded MPSK for the Rayleigh fading channel [PDF]
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 1999 We derive a new upper bound on the pairwise error probability for MPSK sequences over the Rayleigh fading channel when channel state information (CSI) is not available. This is obtained by adding weight factors in calculating the symbol metrics. Simulation shows that the weight factors which optimize the upper bound are likely to optimize the error ...

Analisa Kinerja Pengkodean Kanal Type Reed Solomon Coding pada Kualitas Transmisi Citra
Jurnal Nasional Teknik Elektro, 2018 In the telecommunication systems, the data like audio, image, and video are transmitted to a receiver through a communication channel. However, the presence of noise and fading in the channel will degrade its performance. The degradation may cause error

Frequency estimation in multipath rayleigh-sparse-fading channels [PDF]
, 2004 Maximum-likelihood (ML) data-aided frequency estimation in multipath Rayleigh-fading channels with sparse impulse responses is investigated. We solve this problem under the assumption that the autocorrelation matrix of the pilot signal can be ...

MIMO system capacity based on different numbers of antennas
Results in Engineering, 2022 This paper analyzed and compared the ergodic channel capacities of several typical channel systems (SISO, SIMO, MISO, MIMO) in independent identically distributed flat Rayleigh fading channels. The theoretical and simulation results show that the ergodic

Information Theory of underspread WSSUS channels [PDF]
, 2011 The chapter focuses on the ultimate limit on the rate of reliable communication through Rayleigh-fading channels that satisfy the wide-sense stationary (WSS) and uncorrelated scattering (US) assumptions and are underspread. Therefore, the natural setting

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