Ergodic capacity under channel distribution uncertainty

2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2014
The impact of channel distribution uncertainty on the performance of fading channels is studied. The compound capacity of a class of ergodic fading channels subject to channel distribution uncertainty is obtained, for arbitrary noise and nominal channel distribution.

Ergodic Capacity of Nonlinear MIMO–OFDM Relaying Channels

Wireless Personal Communications, 2014
This paper derives the ergodic capacity of nonlinear MIMO---OFDM relaying communication channels. We consider MIMO---OFDM relaying system where the transmitter, relays, and the receiver are all equipped with $$N_t$$Nt transmitting and $$N_r$$Nr receiving antennas, and the high-power amplifiers (HPAs) at the transmitter and relays exhibit general ...

On ergodic sum capacity of underlay cognitive broadcast channels

21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010
We study the fundamental capacity limits of the underlay cognitive broadcast (BC) channel under average transmit power and average interference power constraints. In a fading environment, the sum capacity is found from a constrained water-filling solution given in [7].

Secrecy capacity of the ergodic layered erasure wiretap channel

2015 49th Annual Conference on Information Sciences and Systems (CISS), 2015
We consider the layered erasure wiretap channel which can also be viewed as the time varying version of the deterministic model of the wiretap channel and characterize its secrecy capacity. We assume an arbitrary fading statistics for the erasure probabilities of the layers and assume that only the fading statistics is known at the transmitter while ...

Ergodic Secrecy Capacity in Nakagami-m Fading Channels

2019 International Carnahan Conference on Security Technology (ICCST), 2019
In this paper, multiple-input-multiple-output wireless communication network is considered: with a base station Alice having multiple antennas, one desired information receiver Bob and one eavesdropper with multiple antennas. A closed-form mathematical expression for the ergodic secrecy capacity under Nakagami-m Fading Channels is derived.

On the Ergodic Capacity of Distributed MIMO Antenna Systems

Wireless Personal Communications, 2016
We consider distributed multiple-input---multiple-output (MIMO) antenna systems, along with their certain generalizations. We show that distributed MIMO configuration can be mapped to a semicorrelated (one side correlated) Wishart model. For a given set of large-scale fading parameters, associated with the path loss and shadow fading, we derive exact ...

Ergodic Capacity Analysis on MIMO Communications in Internet of Vehicles

Mobile Networks and Applications, 2019
Multiple-input multiple-output (MIMO) communications are believed as one of the key enabling technologies to fulfill the increasing requirements of future wireless networks. However, the asymptotic performance limits of MIMO vehicular ad hoc network (VANET) systems are not thoroughly investigated.

Ergodic Capacity of LTE Downlink Multiuser MIMO Systems

2008 IEEE International Conference on Communications, 2008
This paper presents the analysis of the average channel capacity and the SINR distribution for multiuser Multiple Input Multiple Output (MIMO) systems in combination with the base station based packet scheduler. The packet scheduler is used to exploit the available multiuser diversity in the time, frequency and spatial domains.
