In fact, if on the one hand the large transmission bandwidth of IR– UWB signals allows them to resolve multipath components and exploit multipath diversity, on the other hand it yields some new coexistence challenges for both unlicensed commercial and military communication systems, which are required to be robust to unintentional and intentional jammers, respectively. In particular, the design and analysis of low–complexity receiver schemes with good synchronization capabilities and high robustness to Narrow– Band Interference (NBI) is acknowledged as an important issue in IR–UWB research. Motivated by this consideration, in [1] we have recently proposed a low–complexity receiver design, the so– called Chip–Time Differential Transmitted–Reference (Tc–DTR) scheme, and have shown that it is more robust to NBI than other non–coherent receiver schemes available in the literature. In this paper, we aim at generalizing the results in [1] and at developing the enabling analytical tools for the analysis and design of timing acquisition algorithms for non–coherent receivers over frequency–selective fading channels with NBI. Furthermore, we move from the proposed analytical framework to tackle the optimization problem of devising optimal signature codes to reduce the impact of NBI on the performance of the Tc–DTR synchronizer. Analytical frameworks and findings are substantiated via Monte Carlo simulations.","PeriodicalId":330937,"journal":{"name":"2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125772302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Support for network migration, i.e., the ability of a node to seamlessly change its network attachment point without disrupting service sessions, is therefore essential to provide seamless connectivity to warfighters and unmanned autonomous systems. This much needed utility calls for novel middleware to provide mobility functions on top of the traditional communication infrastructure. The goal of this paper is to present the network migration support in Mockets, a communication middleware specifically designed to address the needs of tactical environments by providing handover capabilities transparently and seamlessly to applications. Mockets automatically takes advantage of the best available network, leveraging on predefined, as well as user-provided, policies to perform migration decisions according to the current network status. The performance tests we conducted demonstrate the effectiveness of our implementation and show that Mockets-based network migrations cause an average measured downtime of 17 milliseconds. From a user's perspective, this short interval makes service appear uninterrupted.","PeriodicalId":330937,"journal":{"name":"2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115332554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LinkWayS2 is currently used in the Army's Warfighter Information Network-Tactical (WIN-T) program, the Marine's Support Wide Area Network (SWAN) program and a number of other government programs. The latest development in the LinkWayS2 system take the IP network platform to a new level of performance, with improvements in efficiency, data handling capacity, and security, bringing even more capability to LinkWayS2-based SATCOM terminals. This paper discusses the history of LinkWay and how development has led to the latest improvements to the LinkWayS2 system and their positive implications for the warfighter. These improvements include, for example, a new turbo coded TDMA waveform, doubling the TDMA maximum symbol rate to 10Msps; 8PSK modulation for even higher speed TDMA; pseudo-spread BPSK waveform for mobile and/or disadvantaged terminals, configurable modulation and coding on a per-link basis; embedded TRANSEC; integrated DVB-S2 receiver; increased IP packet processing capability; and enhanced IP QoS. In addition, the overall system architecture has been improved with a new network control server supporting automatic geographic redundancy. Also discussed are recent communications on-the-move (OTM) demonstrations and future enhancements including a further-developed communications on-the-move (OTM) capability through the implementation of a spread spectrum waveform, and even higher data rate handling with improved hardware.","PeriodicalId":330937,"journal":{"name":"2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116124361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
