This paper discusses the distributed nature of airborne software intensive systems. The concept of fly-by-wire, the issues of safety, component communication, and certification are on the forefront of modern airborne applications. Since the communication between variety of onboard systems and subsystems is of paramount importance, the paper discusses the properties of new bus standard based on ...

This paper presents a novel data modulation scheme PCCD-OFDM-ASK: the phase continuous context dependent orthogonal frequency division multiplexing amplitude shift keying. The proposed modulation is successfully applied in the mobile payment system. It is used to transmit the digital data over the speech channel of the mobile communication system GSM, as well as CDMA. The main key points of the...

In this brief we present a design of full-duplex (FD) underwater acoustic communication (UAC) receiver with two-sensor transducer. The transducer consists two piezo-ceramic cylinders cast together in polyurethane resin; one acts as hydrophone and the other projector. As distance between projector is extremely short, high level self-interference (SI) from received at hydrophone. This SI must be ...

In this paper, we investigate the capacity of a point-to-point, full-duplex (FD), wirelessly powered communication system impaired by self-interference. This system is comprised of an energy transmitter (ET) and an energy harvesting user (EHU), both operating in a FD mode. The ET transmits energy towards the EHU. The EHU harvests this energy and uses it to transmit information back to the ET. A...

In this letter, we proposed a shared-antenna fullduplex massive MIMO model for the multiuser MIMO system. This model exploits a single antenna array at the base station (BS) to transmit and receive the signals simultaneously. It has the merits of both the full-duplex system and the time-division duplex (TDD) massive MIMO system, i.e., the high spectral efficiency and the channel reciprocity. We...

Device-to-device (D2D) communications bring significant improvements of spectral efficiency by underlaying cellular networks. However, they also lead to a more deteriorative interference environment for cellular users, especially the users in severely deep fading or shadowing. In this paper, we investigate a relay-based communication scheme in cellular systems, where the D2D communications are ...

In this paper, we discuss a full-duplex (FD) communication scenario, where multiple FD user equipments (UEs) share same spectrum resources (or resource blocks) simultaneously. The FD eNodeB deploys digital precoding and successive interference cancellation with optimal ordering algorithm, to allow coexistence of multiple UEs in downlink and uplink, respectively. The sharing of same resource blo...
