Closed-form Distribution and Analysis of a Combined Nakagami-lognormal Shadowing and Unshadowing Fading Channel

open access: yesJournal of Telecommunications and Information Technology, 2016
The realistic wireless channels face combined (time shared) Nakagami-lognormal shadowing and unshadowing fading because of time varying nature of radio channel and mobile user.

Massive MIMO With Spatially Correlated Rician Fading Channels [PDF]

open access: yesIEEE Transactions on Communications, 2019
This paper considers multi-cell Massive MIMO (multiple-input multiple-output) systems where the channels are spatially correlated Rician fading. The channel model is composed of a deterministic line-of-sight (LoS) path and a stochastic non-line-of-sight (NLoS) component describing a practical spatially correlated multipath environment.

Effective rate analysis of MISO Rician fading channels [PDF]

open access: yes2012 IEEE 7th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2012
The delay constraints imposed by future wireless applications require a suitable metric for assessing their impact on the overall system performance. Since the classical Shannon's ergodic capacity fails to do so, the so-called effective rate was recently established as a rigorous alternative.

Performance Analysis of Hybrid Protocol Based AF EH Relaying over Asymmetric Fading Channels

open access: yesInformation, 2019

A Double-Shadowed Rician Fading Model: A Useful Characterization [PDF]

open access: yes2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC), 2019
In this paper, we provide an alternative characterization for format 1 of the recently proposed double shadowed Rician fading model. Unlike the original definition, both the dominant component and the rms signal are impacted by Nakagami-m processes. For this exposition, we derive analytical expressions for the envelope probability density function (PDF)

On the Bit Error Probability and the Spectral Efficiency of Opportunistic Wireless Transmissions in Rician Fading Channels

open access: yesIEEE Access, 2021
Opportunistic systems take advantage of the wireless communication channel random behavior, since transmission is made only when fading amplitude is above a threshold value, which is calculated based on a transmission probability.

Better than Rician: modelling millimetre wave channels as two-wave with diffuse power

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
This contribution provides experimental evidence for the two-wave with diffuse power (TWDP) fading model. We have conducted two indoor millimetre wave measurement campaigns with directive horn antennas at both link ends.

Blind Joint Soft-Detection Assisted Slow Frequency-Hopping Multicarrier DS-CDMA [PDF]

open access: yes, 2000
A novel multiple-access scheme based on slow frequency-hopping multicarrier direct-sequence, code-division multiple access (SFH/MC DS-CDMA) is proposed and investigated, which can be rendered compatible with the existing second-generation narrow-band ...
