On Low-Resolution ADCs in Practical 5G Millimeter-Wave Massive MIMO Systems
TL;DR: The key transceiver design challenges, including channel estimation, signal detector, channel information feedback and transmit precoding, are discussed and a mixed-ADC architecture is introduced as an alternative technique of improving overall system performance.
Journal ArticleDOI
Performance Analysis of Mixed-ADC Massive MIMO Systems over Rician Fading Channels
TL;DR: This work investigates the performance of mixed-ADC massive MIMO systems over the Rician fading channel, which is more general for the 5G scenarios like Internet of Things, and reveals the tradeoff between the achievable rate and the energy efficiency.

Performance Analysis of Mixed-ADC Massive MIMO Systems over Rician Fading Channels
TL;DR: In this paper, the authors investigated the performance of mixed-ADC massive MIMO systems over the Rician fading channel, which is more general for the 5G scenarios like Internet of Things (IoT).
Journal ArticleDOI
Non-Orthogonal Random Access for 5G Networks
TL;DR: The analysis shows that the performance of the NORA is superior to the conventional orthogonal RA (ORA) scheme in terms of the preamble collision probability, access success probability, and the throughput of RA.
Journal ArticleDOI
New Results on the Fluctuating Two-Ray Model With Arbitrary Fading Parameters and Its Applications
TL;DR: Using a mixture of gamma distributions, new exact analytical expressions for the probability density and cumulative distribution functions of the FTR distribution with arbitrary fading parameters are presented and the performance of digital communication systems over the F TR fading channel is evaluated.
