چکیده
Massive MIMO has become a core technology for the next generation of wireless communications, and non-linear group decoding schemes can achieve better spectral energy efficiency, which in turn leads to higher data rates, especially with assistance non-orthogonal frequency multiple access (NOMA). The purpose this paper is study problems formulating performance such systems. In particular, paper, closely approximates achievable rate large-scale systems occupied by clients (users) using optimal successive (OSGD) scheme mitigate co-channel interference. addition, we produce simple mathematical representation accurately approximate outage probability system. We also formulate effective capacity considered system way. results obtained Monte Carlo simulation show validity derived formulas. findings that increasing number antennas linearly increases expected value decreases its variance. logarithmic manner allocated power. Also, notice distribution random tends be approximated log-normal as increases.

Massive Connectivity with Massive MIMO-Part II: Achievable Rate Characterization
This two-part paper aims to quantify the cost of device activity detection in an uplink massive connectivity scenario with a large number of devices but device activities are sporadic. Part I of this paper shows that in an asymptotic massive multiple-input multiple-output (MIMO) regime, device activity detection can always be made perfect. Part II of this paper subsequently shows that despite t...

Massive multiple-input multiple-output (MIMO) is a promising technology that provides high system capacity, and with excellent performance in energy efficiency and system robustness. However, pilot contamination restricts the system performance due to the limited length of orthogonal training sequences. In this paper, we propose optimization of nonorthogonal pilots for uplink training. The Gras...
