“…If not properly mitigated, SI severely impacts the performance, as it has been reported in [3], [21]. To cope with SI distortion, different mitigation methods, both in the analog and digital domains, have been developed, from which we highlight those based on interference suppression (exploitation of spatial diversity), e.g., [14], [22]- [25], and those based on interference cancellation (generation of an SI replica), e.g., [26]- [30]. Due to insufficient mitigation and high power transmission of the relay, residual SI may still be strong enough to limit performance [14], and, therefore, the relay design must account for the presence of residual SI.…”

“…As a consequence, data signal and SI are correlated, which turns any optimal design strategy into an intractable problem and possibly leading to an unstable system. This is in contrast to DF and CF relays, where the processing delay, defined as the relay input-to-output time delay, is long enough to decorrelate the data signal and the SI [30].…”

We study the problem of optimizing the end-to-end performance of a full-duplex filter-and-forward MIMO relay link, consisting of a source, a relay, and a destination node, by employing linear filtering at each node. The system model accounts for multipath propagation and self-interference at the relay, as well as transmitter impairments and limited dynamic range at every node. The design accommodates signals with arbitrary spectra and includes the direct link between the source and destination nodes. Under the minimum mean square error criterion, the resulting non-convex problem is approximated by a sequence of convex problems and solved by means of an alternating minimization method. Linear constraints allocate some of the degrees of freedom in the relay to guarantee a sufficiently small residual self-interference. Simulations quantify the impact of degrees of freedom, the dynamic range, and the balance between direct and relay paths on the link performance.

“…To simplify the description, we assume that each RUT can only communicate to at most one FAE due to the investment efficiency. In fact, MRT and zero-forcing beam forming (ZFBF) technology in MIMO system [14,20,21] can make one FAE transmit multiple data stream to different users at the same time, and also support multi-devices in transmitting the same file to a receiver simultaneously. The complexity caching scheme for multiple access has been investigated deeply in [5,14], by which the optimum file placement strategy can be found even if a RUT can connect several FAEs and we do not carry out further discussion.…”

The influxes of diversified services and mass data lead to exponential growth of traffic load in mobile cellular networks. Cache-enabled device-to-device (D2D) communication provides a general framework to alleviate this situation. In contrast to previous single-source D2D models, this paper investigates a comprehensive content delivery framework based on a three-tier heterogeneous network (HetNet), where base station (BS), femtocaching auxiliary equipments (FAEs), and user terminals(UTs) are included. The cooperative D2D communication can be implemented from both FAEs and UTs to handle the ongoing explosive increase in ultra-dense scenario. Moreover, duplicate storage for requesting data in multiple neighbor nodes makes many-to-one D2D communication possible at the user layer. Considering the case that cellular users and D2D links reuse the same resources in the uplink period, the non-outage probability of the cellular communication is defined to guarantee the main communication quality. Under the constraints subject to cumulative interference, an optimization objective function based on multi-source D2D communication is deduced to achieve unprecedented average data rate. Numerical simulations show that our system yields network throughput exponentially while transferring traffic load of the BS reasonably.

“…One method to expand the coverage area without using cables is the use of repeaters that convert the frequency of the received wave and retransmit it. Although the practical application of repeaters is technically easy, it is There have been various reports on coupling loop interference cancellers (self-interference cancellers) [3] [4] [5] .…”

Professional wireless cameras using the millimeter-wave band can transmit more information than those in the UHF band, making this band especially useful for transmitting high-quality video and audio with low latency. Although such devices have been put into practical use, there is a need to downsize the equipment on the camera side to reduce expensive millimeter-wave band components and improve operability. In this study, we configure the downlink of a professional wireless camera for UHDTV as a single frequency network (SFN) and study the expansion of coverage provided by a booster. A coupling loop interference canceller and multi-path equalizer are installed in the booster. A computer simulation shows that the booster works well. SFN interference, in which the master and booster waves multiply propagate, can be equalized through frequency domain equalization (FDE) of the single-carrier (SC) system at the receiver side.
