On the ergodic secrecy capacity with full duplex communication [PDF]
2017 IEEE International Conference on Communications (ICC), 2017 Full duplex communication promises performance gains in terms of the throughput and the delay. Generally, it has been shown that the throughput and delay gains of full duplex communication are somewhat limited in realistic network settings, leading researchers to study other possible applications of full duplex communication providing significantly ...

IEEE Access, 2020 Prior works either considered outage capacity of wireless video transmission systems but did not consider NOMA which is a key technology for 5G ultra-reliable low-latency (URLLC), or concerned the ergodic capacity of NOMA-OFDMA systems but did not ...

On the downlink throughput capacity of hybrid wireless networks with massive MIMO
EURASIP Journal on Wireless Communications and Networking, 2018 In this paper, the entire network model is a hybrid wireless network model in which each base station is connected to each other via a wired link. On this basis, we place a large number of antennas (massive MIMO) at each base station to serve a single ...

Distortion Metrics of Composite Channels with Receiver Side Information [PDF]
, 2007 We consider transmission of stationary ergodic sources over non-ergodic composite channels with channel state information at the receiver (CSIR). Previously we introduced alternative capacity definitions to Shannon capacity, including outage and expected

A Unified Framework for the Ergodic Capacity of Spectrum Sharing Cognitive Radio Systems [PDF]
, 2012 We consider a spectrum sharing communication scenario in which a primary and a secondary users are communicating, simultaneously, with their respective destinations using the same frequency carrier.

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

Upper Bounds for the Capacity for Severely Fading MIMO Channels under a Scale Mixture Assumption
Entropy, 2021 A cornerstone in the modeling of wireless communication is MIMO systems, where a complex matrix variate normal assumption is often made for the underlying distribution of the propagation matrix. A popular measure of information, namely capacity, is often

SVD-based IWFA for next generation wireless MIMO communication
ICT Express, 2018 Point-to-point MIMO systems without channel state information at the transmitter (No CSIT) and with perfect channel state information at the transmitter (Perfect CSIT) were considered for the application of a novel singular-value-decomposition-based (SVD-

Ergodic Capacity of NOMA-Based Uplink Satellite Networks With Randomly Deployed Users
IEEE Systems Journal, 2020 Allowing multiple users access simultaneously, a power-domain nonorthogonal multiple access (NOMA) scheme can provide enhanced resource utilization efficiency and has been viewed as a promising strategy in the satellite networks, to provide high quality ...

Ergodic Capacity Under Power Adaption Over Fisher–Snedecor ${\mathcal{F}}$ Fading Channels [PDF]
IEEE Communications Letters, 2019 In this letter, we consider a communication scenario, where the transmitter adopts different power adaption methods according to the instantaneous channel state to enhance the ergodic capacity (EC) over Fisher–Snedecor $\mathcal {F}$ fading channels ...
