This paper studies the massive MIMO full-duplex relaying (MM-FDR), where multiple source-destination pairs communicate simultaneously with the help of a common full-duplex relay equipped with very large antenna arrays. Different from the traditional MM-FDR protocol, a general model where sources/destinations are allowed to equip with multiple antennas is(More)
This paper proposes an amplify-and-forward-based massive multiple-input-multiple-output full-duplex relaying (AF-MM-FDR) protocol, where multiple source-destination pairs communicate simultaneously with a common full-duplex relay. A zero-forcing (ZF)-based relay transceiver design with semiblind gain control is presented, considering the problem of relay(More)
This paper investigates a multi-pair two-way massive MIMO amplify-and-forward full-duplex relay (FDR) system over Ricean fading channels, where multiple pairs of full-duplex users exchange information within pair through a full-duplex relay with a very large number of antennas (M for transmission and M for reception). First, the zero-forcing(More)
This paper investigates the multi-pair full-duplex massive MIMO relaying, where multiple source-destination pairs communicate simultaneously with the help of a common full-duplex decode-and-forward relay. It is assumed that the sources and destinations are equipped with single antenna while the relay is equipped with very large antenna arrays. The(More)
In this paper, we investigate the outage performance of time division broadcasting (TDBC) protocol in independent but non-identical Rayleigh flat-fading channels, where all nodes are interfered by a finite number of co-channel interferers. We assume that the relay operates in the amplified-and-forward mode. A tight lower bound as well as the asymptotic(More)
The average symbol-error-rate (SER) performances for the three-phase two-way relaying (TWR) protocols are analyzed and compared in Rayleigh fading channels, where the terminals and relay are interfered with by a finite number of cochannel interferers. The relay is assumed to operate in the decode-and-forward (DF) mode. Three TWR protocols where the(More)
Opportunistic relay selection (RS) is an efficient method to obtain diversity gain in analogue network coding (ANC) protocol with multiple relays. However, in networks with mobile relays, the channel state information (CSI) used in the RS procedure becomes outdated because of the time-varying nature of fading channels, which severely deteriorates the system(More)
This paper considers the transceiver design and antenna subset selection for cooperative half-duplex relaying (HDR) and full-duplex relaying (FDR) protocols. We first present the low-complexity transceiver design for given antenna subset at each node. Then the antenna subset selection schemes for both FDR and HDR protocols are proposed and evaluated in the(More)
In this paper, we analyze the performance of two-way relaying (TWR) protocol in Rayleigh fading channels, where the terminals and relay are interfered by a finite number of co-channel interferers. The relay is assumed to operate in the decode-and-forward mode. The average symbol error rate (SER) performance for binary phase shift keying (BPSK) is analyzed.(More)
