This use of PBSM is a paradigm shift in the way DoD will manage the use of the electromagnetic spectrum in support of Dynamic Spectrum Access (DSA) enabled Policy Based Radios (PBRs). The multifaceted implications of PBSM need to be understood so that required changes to spectrum-related business processes (and the data and automated capabilities used within these processes) can be identified and coordinated with stakeholders. A major element of PBSM is the generation, distribution, and consumption of Digital Spectrum Policy (DSP) by DSA-enabled PBRs. The US Army Communications Electronics Research Development Engineering Center (CERDEC) is developing a broad set of DSA/PBSM-related capabilities including tools to generate DSP. The Defense Information Systems Agency Defense Spectrum Organization (DSO) is developing enterprise solutions for DSA/PBSM. CERDEC and DSO collaborated with BAE Systems and Applied Communication Sciences on the development of an end-to-end PBSM architecture called DSA Policy Management Architecture (DPMA). This paper presents a summary of the architecture development.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"40 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79615284","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}

Cooperative relaying technique is a promising technique to provide high rate data transmission. However, literature on cooperative communications in UWA environments is very scarce. In this paper, we propose a novel UWA cooperative communication system, which involves the wave cooperative (WC) transmission protocol, Orthogonal Frequency Division Multiplexing (OFDM) and the Lloyd algorithm-based limited feedback procedure for the first time. We take capacity criterion-based power allocation strategy as an example to demonstrate the performance of our proposed system. Simulation results show the system capacity performance based on uniform allocation (non-feedback), several bits of feedback and perfect feedback. Furthermore, simulation results compare the performance between the WC transmission protocol and the traditional amplify-and-forward (AF) transmission protocol.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"258 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83502876","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}

In this paper, we present an effort to design, develop, test and demonstrate an interoperable coalition interface for a Naval Task Force for the four-nation Coalition Networks for Secure Information Sharing (CoNSIS) project. A field experimentation has been performed between the four CoNSIS nations with the separate national sites being connected via the Internet. The key architectural objective of the United States (US) is to support tactical coalition networks of the other nations. The routing architecture is based on Open Shortest Path First Version 3 (OSPFv3) in conjunction with two main features, namely (1) IPv6 address auto configuration enabled on mobile links to alleviate administrative burden, and (2) Address Family (AF) support to allow IPv4 traffic to be passed via IPv6 backbone. In addition, Point-to-Point Protocol over Ethernet (PPPoE) with Flow Credit and Link Metric extensions is used to provide mobile networks via point-to-multipoint links with support for Quality of Service (QoS). Furthermore, link encryptors secure the network, which make use of Dynamic Discovery mechanisms to determine remote routing endpoints.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"67 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86116193","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}

This paper proposes a new algorithm which attains the ML performance with significantly reduced complexity. The proposed scheme is based on combining Branch and Bound algorithm (which solves an integer quadratic programming (IQP) problem in each node of the search tree) with M-Algorithm (which chooses M reliable candidates nodes out of the available nodes, in each stage of the search tree, and retain them) and hence we call it BB-M algorithm. The basic idea is analogues to the conventional QRD-M that presented in the literature, but the internal procedures of the algorithm is different, as the proposed algorithm uses the IQP based on BB algorithm. Not just that but also to reach maximum likelihood (ML) performance, the M value in BB-M is less than M in QRD-M. Simulation results show that the proposed detection scheme provides comparable performance to the ML at small M with fixed complexity regardless of the SNR and the constellation size. Hence, it is a promising scheme for optimal and near optimal performance of MIMO systems when adopting higher order QAM constellations.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"130 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73312103","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}

A simple linear-conjugate linear periodically time-varying operator called a FREquency SHift (FRESH) properizer is proposed to perform this conversion. As an application, we consider the presence detection of an improper-complex SOCS random process, which well models the complex envelopes of digitally modulated signals such as pulse amplitude modulation (PAM), staggered quaternary phase-shift keying (SQPSK), Gaussian minimum shift keying (GMSK), etc. In particular, the optimal presence detector that utilizes the FRESH properizer is derived for improper-complex SOCS Gaussian random processes, which provides the lower bound on the detection error probabilities. The derived optimal detector, which has the structural advantage in that it consists of a FRESH properizer followed by a single linear filter, achieves the same performance as the conventional detector that consists of parallel-connected linear and conjugate-linear filters. Numerical results are also provided.","PeriodicalId":18720,"journal":{"name":"MILCOM 2012 - 2012 IEEE Military Communications Conference","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90599647","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}
