Dynamic Spectrum Access (DSA) and Cognitive Radio (CR) have been considered promising to enhance the efficiency and utilization of the spectrum. In current overlay cognitive radio, spectrum sensing is first performed to detect the spectrum holes for the secondary user to harness. However, in a more sophisticated cognitive radio, the secondary user needs to detect more than just the existence of primary users and spectrum holes. For example, in a hybrid overlay/underlay cognitive radio, the secondary use needs to detect the transmission power and localization of the primary users as well. In this paper, we combine the spectrum sensing and primary user power/localization detection together, and propose to jointly detect not only the existence of primary users but the power and localization of them via compressed sensing. Simulation results including the miss detection probability (MDP), false alarm probability (FAP) and reconstruction probability (RP) confirm the effectiveness and robustness of the proposed method.","PeriodicalId":330937,"journal":{"name":"2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE","volume":"24 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":"116195745","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}

The transmitter encompasses 12 electro-absorptive modulated lasers (EMLs) with wavelength channels from 1270nm to 1380nm on a 10nm channel grid. The lasers are grouped in three (3) arrays with each array monolithically integrating four (4) EMLs operating at 43Gbps each. The three EML arrays are flip-chip bonded to a planar light-guide circuit (PLC), which serves as the mounting platform and provides the optical multiplexer function. The receiver couples the signal through an optical PLC-based de-multiplexer to twelve (12) high-speed PIN detectors with a 3dB bandwidth of more than 50GHz. The transmission tests were performed over 2km of SMF with each channel tested at 40Gbps. For the demonstration, a commercial semiconductor optical amplifier was used in front of the receiver to boost the signal. Each channel was tested to be error free to <10−11 BER with most <10−12 BER. The total cross-talk was measured to be between 1 and 2dB. The channel spacing of 10nm was chosen to enable a low cost transmitter operation without using Thermo-Electric-Coolers (TEC) in order to reduce the overall power dissipation. Instead of a TEC, resistive heating can be used to limit the temperature excursions and to enable an operating range of the TOSA from −5 to +75 deg C. This technology demonstration is a step towards the final goal of 1 Terabit/s transmission for Datacenter applications.","PeriodicalId":330937,"journal":{"name":"2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE","volume":"4 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":"125570179","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}

DSA allows network operators to adapt to last minute spectrum assignment planning changes as well as changes made after deployment. DSA also allows the radios to overcome even unplanned, unexpected interference sources. The technology was initially developed for the DARPA XG program, and now several military radio platforms are currently being extended to integrate the technology. We present a case study of dynamic spectrum access software technical and operational integration challenges. We also present the benefits from developing and deploying a single core radio software application that follows commercial iPhone-like solutions. We describe an approach that obviates many problems by abstracting radio components into a set of device classes. We also define an open application-programming interface for interacting between the device classes and the dynamic spectrum access components. We have defined an open management interface for allowing consistent spectrum management across all platforms. This approach supports a scalable proliferation of the technology, future enhancements across platforms, and provides compatible spectrum management paradigm across platforms. This also enables upgrades performed in a consistent fashion. Our experience and results show that the approach performs well across heterogeneous military radio platforms with vastly varied hardware and software features. This software-only extension is achieved via adaptively collecting, analyzing, and responding to radio's spectral environment at runtime. This paper is a case study of lessons learned, challenges with network and waveform integration, and a roadmap for other dynamic access spectrum developers to consider in future applications.","PeriodicalId":330937,"journal":{"name":"2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE","volume":"1 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":"130101812","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}
