Abstract: In the multiuser MIMO system, the quality of service (QoS) is an important issue especially for cell edge users in multi-cell downlink system. The utilization of multiple-input multiple-output (MIMO) relay stations (RSs) provides solution for improving the signal-to-interference plus noise ratio (SINR) from neighbouring base station (BSs) to each relay station (RS). In the design of t...

There has recently been a resurgence in the idea that amnesia may be characterized by an increased susceptibility to interference. In the present study we tested this idea using a well-controlled and well-established animal model of amnesia: impairment in object recognition following perirhinal and postrhinal cortical (PPRh) damage. We used this paradigm to test whether memory impairment was ex...

We present a novel variant of decision making based on the mathematical theory of separable Hilbert spaces. This mathematical structure captures the effect of superposition of composite prospects, including many incorporated intentions, which allows us to describe a variety of interesting fallacies and anomalies that have been reported to particularize the decision making of real human beings. ...

This paper studies interference alignment scheme and minimum mean square error (MMSE) improvement in Internet of Things (IoT)-oriented cognitive systems, where IoT devices share the licensed spectrum by cognitive radio in spectrum underlay. Target to manage the inter-tier interference caused by cognitive spectrum sharing as well as ensure an MMSE at receivers, the interference alignment algorit...

It is very important that the radar sensor network has autonomous capabilities such as self-managing, etc. Quite often, MIMO interference channels are applied to radar sensor networks, and for self-managing purpose, interference management in MIMO interference channels is critical. Interference alignment (IA) has the potential to dramatically improve system throughput by effectively mitigating ...

the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

background and aims: inhibition of viral growth in coinfected cells with two different viruses has been described. this phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. in this study we superinfected reovirus infected hela cells with poliovirus to determine if poliovirus can replicate in s...

In this paper, we investigate the optimisation of the Random Access CHannel (RACH) of the UMTS FDD system in terms of generated interference. Conditional on open loop measurements, we search the best initial energy of the RACH in order to reduce the multiple access interference while keeping a reasonable mean access time.

With a picture-picture experiment, we contrasted competitive and non-competitive models of lexical selection during language production. Participants produced novel noun-noun compounds in response to two adjacently displayed objects that were categorically related or unrelated (e.g., depicted objects: apple and cherry; naming response: "apple-cherry"). We observed semantic interference, with sl...

Radio controlled clocks (RCCs) based on the WWVB broadcast, commonly referred to as “atomic clocks”, might experience relatively high levels of on-frequency interference from the equivalent MSF time-code broadcast from the UK, particularly on the East Coast. The problem may be further exacerbated by a random orientation of the RCC device, which might favor the reception of the interfering signa...
