Error-bound formulation for multichannel reception of M-DPSK and pilot-aided M-PSK over Rayleigh-fading channels with postdetection combining [PDF]

open access: yes, 2004
Upper bounds for symbol-error probability are developed for multichannel reception of M-ary phase-shift keying (M-PSK) over frequency-flat Rayleigh-fading channels.

Analytical evaluation of adaptive-modulation-based opportunistic cognitive radio in Nakagami-m fading channels [PDF]

open access: yes, 2012
The performance of adaptive modulation for cognitive radio with opportunistic access is analyzed by considering the effects of spectrum sensing, primary user (PU) traffic, and time delay for Nakagami- m fading channels.

Capacity of κ-μ Shadowed Fading Channels

open access: yesInternational Journal of Antennas and Propagation, 2014
The ergodic capacity of fading channels modeled with a κ-μ shadowed distribution is investigated to derive closed-form expressions. The κ-μ shadowed distribution is of particular interest because it contains, as special cases, other classical ones like ...

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.

On the Capacity of MIMO-MAC in Rician channel [PDF]

open access: yesThe Egyptian International Journal of Engineering Sciences and Technology, 2021
The information theoretic limits for the single user MIMO (Nt×Nr) communication channel are well established in literature for different scenarios of channel types and channel state information (CSI) availability. However, all obtained results are based on the linear system model in which the channel transfer function is defined as a single entity in ...

Joint User Identification and Channel Estimation Over Rician Fading Channels [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2020
This paper considers crowded massive multiple input multiple output (MIMO) communications over a Rician fading channel, where the number of users is much greater than the number of available pilot sequences. A joint user identification and line-of-sight (LOS) component derivation algorithm is proposed without requiring a threshold. Based on the derived

Modeling Analysis for Downlink RIS-UAV-Assisted NOMA over Air-to-Ground Line-of-Sight Rician Channels

open access: yesDrones
This paper proposes a drone-assisted NOMA communication system equipped with a reconfigurable intelligent surface (RIS). Given the Line-of-Sight nature of the Air-to-Ground link, a more realistic Rician fading environment is chosen for the study of ...

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.

Downlink Steered Space-Time Spreading For Multi-Carrier Transmission Over Frequency Selective Channels [PDF]

open access: yes, 2008
This paper presents a novel amalgam of Steered Space-Time Spreading (SSTS) and Orthogonal Frequency Division Multiple Access (OFDMA) designed for attaining both spatial diversity gain and beamforming gain for transmission over OFDM-symbol-invariant ...
