In OFDM-based systems the effect of nonlinear amplification at the transmitter is increasingly being tackled by receiver-oriented methods that aim to reduce distortion through estimating and recovering the clipped signal. However, in OFDMA systems, recovery of clipped signals poses new challenges because not all modulation information about other users is available to any individual user. Recently a scheme based on simple clip localization and band limited signal recovery has been proposed to address this problem but its performance is limited. In this paper, we propose to improve clip location estimation by exploiting key factors such as closeness of signal level to clipping threshold, clip time-span, and out-of-band power for local windowed subsequences, and then incorporate clip location estimates in iterative projection method to recover the clipped signal. Extensive simulations demonstrate that the performance is significantly improved with the proposed scheme compared with existing methods.

Compared the measurement results in two different bandwidths, Ultra-wide band (UWB 3-10 GHz) and Narrow Band (NB 402MHz). We figured out the multi path situation by comparing the measurement results in empty flat box and in the homogenous tissue. The maximum distance of the measurement in this paper is 9 cm considering the huge path-loss in UWB measurement. Based on the analysis of the DME, the TOA of the first peak in UWB measurement and the phase of signal in narrowband measurement can both provide the accurate location information for BAN application.

Mobile ad-hoc networks (MANETs) enable operation without fixed infrastructure, making them attractive for disaster search and rescue (SAR) and tactical applications. Reliability is an issue in such applications and increasing MANET communication reliability is critical for the acceptance of these systems. In this paper we investigate the impact of feedback delay on adaptive modulation and coding (AMC) in VHF narrowband MANETs. We analyse communication reliability and quality of service (QoS) under realistic conditions and study user net throughput and packet delivery ratio (PDR) for various AMC feedback delays using Monte Carlo computer simulation. We show that feedback delays of multiple frame durations are tolerable even for higher velocities (300 km/h) without significant reliability issues, on the other hand for high delays the system trades throughput for reliability.

This paper proposes an improved QoS scheduling scheme, called the Modified Proportional Fairness with MultiHop (MPF-MH) algorithm for Cognitive Radio Mobile Ad Hoc Networks (CR MANET). Within the context of multi-channel MAC enabled networks, mobile nodes can experience simultaneous transmission across multiple channels. Benefiting from the proposed cross layer design, the real-time channel conditions provided by CR function permits adaptive subchannel selection for each transmission. MPF-MH adaptively schedules the radio resources for serving different types of service in order to optimize network resources without decreasing the quality of service. Simulation results confirm that MPF-MH provides good QoS guaranteed performance across a variety of CR MANET scenarios.

Dynamic spectrum access in the cognitive radio network can make use of spectrum holes by chance. It can improve the efficiency of spectrum utilization without degrading the primary users (PUs). We propose a new method to assign channels in multi-hop cognitive radio networks. First of all, we choose a reasonable spectrum perception approach to sense if the PUs use the channel in each time slot. The transmission ranges of secondary users (SUs) are determined according to the PUs. In our method, the SUs can not only use the channels when the PUs not send messages via it, but it can also use the channel with the PUs at the same time as long as the cover scope of the transmission nodes is appropriately controlled. Simulations results show that our method can raise the successful connectivity probability from one SU to another SU without interfering PUs.
认知无线网络中的动态频谱接入可以随机利用频谱空穴。它可以在不降低主用户(primary user, pu)的情况下提高频谱利用效率。提出了一种新的多跳认知无线网络信道分配方法。首先，我们选择一种合理的频谱感知方法来检测pu是否在每个时隙中使用信道。secondary user (secondary user)的传输范围根据pu的大小来确定。在我们的方法中，su不仅可以在pu不通过它发送消息时使用通道，而且只要适当控制传输节点的覆盖范围，它也可以与pu同时使用通道。仿真结果表明，该方法可以在不干扰pu的情况下提高SU之间成功连接的概率。

Increasingly, unlicensed devices demand access to the licensed wireless spectrum, raising the problem of spectrum scarcity. This problem can be addressed by allowing unlicensed devices opportunistic access. Because opportunistic devices regard licensed users as interference, channel Signal to Interference Noise Ratio (SINR) is an important consideration for transmission. Cognitive Radio (CR) technology allows devices to sense spectrum and dynamically allocate bits to channels with good SINR. In this paper we introduce a stochastic modulation algorithm called the Cognitive Radio Stochastic Modulation (CRSM), for use as an extension to established M-ary Modulation schemes in underlay channels with poor SINR. In this modulation scheme, in additive channels, both the transmitting and receiving CR sense the magnitude and variance of the interference energy in the channel. The transmitter uses deterministic signals as unique identifiers in manipulating the variance of the signal detected at the receiver. The detected change in variance, measured at the receiver, is indicative of the presence or absence of a signal. In this paper we determine the critical regions for the CRSM and introduce a probability of error model.

Distributed approaches to face recognition have been widely studied for over a decade. One of the remaining problems with these approaches is that of coordinating the heavy storage requirements in a distributed way. We present a modification of existing facial recognition algorithms deployed on a self organizing, reliable and robust platform composed of wireless sensor nodes that should yield a self-organizing algorithm for face recognition, which manages its storage in an entirely distributed way. Our preliminary results, though tentative, suggest that these expectations are plausible. As an effective facial recognition algorithm, our implementation is still a work in progress; but the modest computational requirements of the storage platform, coupled with the parallelizable operations already in current distributed face recognition techniques should eventually yield a distributed algorithm that can be scaled up to run on a very large system of simple processors.

Femtocells have come up as a promising solution for indoor coverage and Quality of Service, QoS of the users. One of the major challenges in the wide deployment of the femtocells is the cross-tier interference among the users at the cell edges. A typical high interference case is the uplink interference caused by the non subscribed cell edge users at the closed mode femtocells. In dense urban scenarios this interference may occur frequently resulting in the high deterioration of the femtocell capacity and QoS of the users; thus affecting the over all cell throughput. Fractional Frequency Reuse, FFR based schemes are a common option to cater the problem. Although efficient in interference avoidance, FFR results in lower cell throughput. The proposed scheme is an effective threshold based interference avoidance scheme working on the principles of Universal Frequency Reuse, UFR to obtain higher cell throughput. The information of femtocells location or their power settings are not required in the approach. Consequently it requires minimum backhaul signalling between the macrocell and the femtocells. Simulation results show significant improvement of the proposed scheme in terms of macrocell throughput, spectral efficiency and SINR of the femtocell user.

Quality of Service (QoS) differentiation measurement provides the ability to evaluate different level of QoS support in 4G networks such as Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX). Many research studies around the world have addressed the QoS Differentiation (QoS-Diff) considerations, however, to the best of our knowledge, only a few have attempted to make measurements and evaluate the level at which each QoS solution could provide differentiated services to users and applications in demand. In this study, we provide a method to evaluate such differentiated level of service by means of User as well as Service Provider satisfaction levels, and use a new parameter to measure them. By simulation results, we show that this parameter could provide detailed information about QoS-Diff measurements and how users and service providers perceive their service delivery experience.

There are more and more mobile applications developed and used. With the number of cloud services increasing daily, it is more and more important to satisfy quality of service from the perspective of the customer's service requests. A proper service selection system is critical to solve this problem. A framework from modeling to design, and to implementation is proposed to build a service selection system. A Markov chain model is used for performance measures calculation. The service selection optimization problem is followed, as well as a proposal of dataflow based implementation.
