We discuss channel acquisition and tracking in the uplink of a multi-carrier code-division multiple-access (MC-CDMA) system. Channel acquisition is performed jointly with noise power estimation following two different approaches. The first assumes independently faded subcarriers while the second exploits the fading correlation across the signal bandwidth to improve the system performance. Both schemes are based on maximum likelihood (ML) reasoning and exploit some training blocks carrying known symbols. Channel tracking is pursued through least-mean square (LMS) techniques, using data decisions provided by a partial parallel interference cancellation (PPIC) receiver

The choose to perform a C-OFDM modulation directly by satellite makes the design of cost-effective new communication scenarios possible, in periods in which satellite communications call for a higher penetration in everyday services provision, avoiding the high costs of terrestrial-segment infrastructures to make the satellite signal exploitable by mobile users in urban environments. This paper focuses on the analysis of the performances of a C-OFDM-based communication scheme for the provision of a high quality and scalable bit rate radio signal over satellite links and exploitable in urban environments. Due to these preambles, the almost unemployed specifically satellite-oriented Mode-III of the DAB standard is considered, in conjunction with the design of an high-effective receiver based on soft-decision schemes, in cohabitation with almost very spread terrestrial DAB services. The degradations due to propagation and signal distortions introduced by the payload are also taken into account in the analysis of the transmission system

With network operators migrating from circuit-switched networks to IP networks, the need for a concept to provide operator grade trunk signaling over IP arises. A solution to enable signaling transport over IP is defined by the IETF SIGTRAN framework that allows for interworking with the Signaling System No. 7 (SS7). SIGTRAN is based on the stream control transmission protocol (SCTP) that also has a built-in redundancy mechanism, which allows switching to an alternative destination address (failover). Existing work showed that a failover performance comparable to SS7 can be achieved by aggressively setting the SCTP protocol parameters. However, this brings about possible stability issues because these parameter settings seriously impair the protocol mechanisms responsible for reacting to delay variations and congestion situations. We propose a set of network redundancy mechanisms that resolve most network failures transparently to SCTP. In order to eliminate possible stability issues, we use the default SCTP protocol parameters. Simulation results confirm that the proposed architecture can noticeably improve the robustness to concurrent network failures and achieve a similar delay behavior without jeopardizing the protocol stability

A simple technique to estimate the position of a given mobile source inside a building is based on the received signal strength. For this methodology to have a reasonable accuracy, radio visibility of the mobile by at least three access points is required. To reduce the number of the required access points and therefore, simplify the underlying coverage design problem, we propose a new scheme that takes into account the distribution of RF energy around the receiver. In other words, we assume that the receiver is equipped with a circular antenna with beamforming capability. In this way, the spatial spectrum of the received power can be measured by rotating the antenna beam around the 360-degree field of view. This spatial spectrum can be used by a single receiver as a mean for estimating the position of a mobile transmitter. In this paper, we investigate the feasibility of this methodology, and show the improvement achieved in the positioning accuracy

In this paper, we propose a practical approach to address how micro-mobility can be provided in an efficient way with continuous quality of service (QoS) support. Our proposal is based on multiprotocol label switching (MPLS) and mobile IP and relies on two-level hierarchy architecture. It supports two protocol variants. First, the fast handoff process, which anticipates the LSPs procedure setup with the neighboring locations where a mobile node (MN) may move to, is provided to reduce the service disruption. Second, a new mechanism based on the forwarding chain concept is proposed to track efficiently the host mobility within a domain. This concept can significantly reduce the registration updates cost and provide low handoff latency. Analytical models are developed and simulations are conducted to justify the benefits of our proposed mechanisms

This paper presents a model for the link service capacity that an imperfect adaptive radio link provides to upper layers. As the main contribution of this paper, the model includes a number of imperfections in the link adaptation chain, as well as implementation implications. The average goodput is expressed also in compact form and its dependence on the impairments is discussed using analytical, numerical, and simulations results. The model, to be used for analyses at upper layers, integrates physical channel, transceiver characteristics, and imperfections in a flexible way, by independent, separate matrices

We study the geometry of the feasible MSE region of multiuser MIMO systems with fixed transmitters and receivers. The sum of all powers is assumed to be constrained. We consider both linear processing and non-linear processing, i.e., interference precompensation in the downlink and successive interference cancellation in the uplink. We show that, for both cases, the feasible MSE region of uplink and downlink is a convex set. In addition, we show for adaptive multiuser reception/preceding, that the maximal feasible MSE region for two-user beamforming systems with adaptive MMSE filtering are convex

An important parameter of MIMO channel models is the cluster root-mean-square (rms) directional spread. In this paper we determine this parameter in the azimuth-of-arrival/azimuth-of-departure (AoA/AoD) domain based on comprehensive indoor MIMO measurements at 5.2 GHz in a cluttered office environment. This is done in a four-step procedure: (i) the SAGE algorithm is used to extract propagation paths, (ii) clusters of estimated paths in the double-azimuth domain are defined, (iii) the estimated propagation paths are allocated to the clusters, (iv) the cluster directional spreads are estimated based solely on propagation paths within the clusters. We found that the spreads are different when seen from transmitter or receiver due to different propagation conditions resulting in AoD rms cluster spreads lying in the range from 2 to 9 degrees and AoA rms cluster spreads in the range from 2 to 7 degrees

The provisioning of value-added-services (VAS) to mobile users is crucial for the proliferation and early adoption of converged voice and data networks, 3rd generation/beyond 3rd generation networks (3G/B3G). In this paper, we describe a VAS provisioning middleware framework for deployment in 3G mobile operator networks. Through this framework, we enable on-demand selection of 3rd party services in 3G/B3G networks. The main contribution, in terms of novelty, is that the framework introduces a new service provisioning paradigm called on demand service selection. The service selection (a requested user task can be accomplished by many similar service offerings, therefore the need for selecting a particular service) is driven by the 3G operator business policies, user profile/preferences and runtime context information. Also, the framework adapts the service selection to changing business-technical performances of the 3rd party CP/SP, and specific user preferences and context

In this paper, we shed some light on the implications that using a recently proposed layered space-time multiuser detection technique has on MAC protocol design for ad hoc networks with multiple antennas. From this point of view, our work relates to both physical layer and network layer studies. In fact, on the one hand physical layer aspects are important to characterize the behavior at the receiver, especially in terms of bit and packet error rates, but are rarely considered in conjunction with networking scenarios; on the other hand, networking aspects are typically studied using drastically simplified physical layer models that, while allowing easier networking analysis, are often too restrictive or unrealistic. Also, this disconnects between physical and networking layer studies may severely limit the possibilities for cross-layer optimization, which appears to be the right approach for efficient wireless network design. Our paper is then an effort to establish some connection between the "physical" and "network" approaches, highlighting some interesting capabilities that ad hoc networks with multiple antennas are endowed by the use of multiuser detection
