Most existing works on orthogonal frequency division multiple access (OFDMA) multihop
cellular networks have assumed half-duplex relay, which suffers from spectral inefficiency …

We consider a parallel two-way relaying orthogonal frequency division multiple access
(PTWR-OFDMA) scheme based on analog network coding in which mobile terminals (MTs) …

This paper considers a relay-assisted bidirectional cellular network where the base station
(BS) communicates with each mobile station (MS) using orthogonal frequency-division …

Recently, full duplex (FD) has been attracting great attention, due to its capability to double
the spectral efficiency. In this paper, we focus on a FD wireless communication network, in …

This study investigates a relay‐assisted orthogonal frequency division multiple access
cellular system with joint consideration of direct and relaying paths. In this system, a novel …

In this paper, we propose a new cell architecture for the orthogonal frequency division
multiple access (OFDMA) systems by jointly taking frequency allocation scheme (FAS) and …

In this paper, we propose a simple linear multiuser precoding scheme for downlink cellular
systems with a decode-and forward (DF) based relay, where the available information at a …

In two-hop relay-aided cellular networks, both half-duplex (HD) and full-duplex (FD)
transmission have been extensively studied. FD transmission can achieve twice throughput …

Two-way relaying, which enables bidirectional simultaneous data transmission between two
nodes, is an efficient means to reduce the spectral efficiency loss observed in conventional …

Device-to-device (D2D) communications, which can increase system throughput, allow two
cellular devices to communicate directly with each other. Compared with half-duplex relay …
