We consider the use of multiple intelligent reflecting surfaces (IRSs) in cell-free massive
MIMO (CFMM) systems to improve signal quality. However, pilot contamination can occur …

We propose a novel graph-theoretical dynamic user pairing strategy based on the user rate
requirements in cellular networks employing non-orthogonal multiple access (NOMA). The …

This paper considers a non-orthogonal multiple access (NOMA) downlink network, where a
hybrid of NOMA and beamforming designs is developed to enhance the channel capacity …

In this contribution, the optimization of power proportion allocated for each user in the
downlink (DL) nonorthogonal multiple access (NOMA) systems have been developed …

This study investigates a combined system comprising non-orthogonal multiple access
(NOMA) and beamforming in a downlink network. To fully exploit the advantages of NOMA …

In 6G wireless communication systems, Nonorthogonal multiple access (NOMA) can solve
the problem of extra consumption power and bandwidth to enhance the spectral-efficiency …

Given two sets of objects, the integer assignment problem consists of assigning objects of
one set to objects in the other set. Traditionally, the goal of this problem is to find an …

This paper investigates an optimization problem of the joint user association and power
allocation for max-min fairness in downlink multicell non-orthogonal multiple access (NOMA) …

In 5G wireless communication systems, Non-orthogonal multiple access (NOMA) is a
technique for improving the spectral-efficiency (SE) of the systems by supporting massive …

In non orthogonal multiple access (NOMA), the base station transmits data to weak and
strong users randomly chosen. In this paper, we suggest two strategies for users' paring …
