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 ...

Approaching the ergodic capacity with lattice coding [PDF]
2014 IEEE Global Communications Conference, 2014 It is known that lattice coding can achieve the capacity of the additive white Gaussian noise (AWGN) channel. This paper addresses the performance of lattice codes in the ergodic fading channel. Using nested lattice codes and ambiguity decoding, we show that the rates achieved by lattice coding and decoding are within a constant gap of the capacity of ...

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 ...

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

Evaluating pointing errors on ergodic capacity of DF relay-assisted FSO communication systems [PDF]
, 2015 Ergodic capacity of decode-and-forward (DF) relay-assisted free-space optical (FSO) communication systems when line of sight is available is analyzed over gamma-gamma fading channels with pointing errors.

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 ...

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 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 ...

On the MIMO Capacity with Residual Transceiver Hardware Impairments [PDF]
, 2014 Radio-frequency (RF) impairments in the transceiver hardware of communication systems (e.g., phase noise (PN), high power amplifier (HPA) nonlinearities, or in-phase/quadrature-phase (I/Q) imbalance) can severely degrade the performance of traditional ...
