The initial operating capability for the DoD directory is planned for 1995 to meet a validated requirement for an X.500 directory to support the Defense Message System. Continued trends in computer processing and data storage provide DoD with economical alternatives for integrating existing paper-based and proprietary electronic directories.<<ETX>>","PeriodicalId":394587,"journal":{"name":"MILCOM 92 Conference Record","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131147215","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}

These agreements will replace the existing liaison procedures for providing cooperation and understanding between commanders and staffs of headquarters and forces that are working together. The design and operation of an interface unit that provides voice interoperability and the plan for an interface unit that will provide both voice and data interoperability are described. The key factor in each design is that NATO members can design and build their own portion of the interface units to be compatible with their particular systems. The only requirement is that the interconnecting cable and signals over the cable be in accordance with the standard. The cable for the voice-only interface unit is a shielded multiconductor metallic cable. A fiber-optic cable has been proposed for the voice and data interface.<<ETX>>","PeriodicalId":394587,"journal":{"name":"MILCOM 92 Conference Record","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131398092","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}

IT provides full duplex VHF radio communications to mobile users, with TRANSEC and COMSEC protection, offering the same numbering scheme and services as for the static subscribers. The SCRA can also work in stand-alone mode as an autonomous communication center ideal for quickly deploying troops operating far from the rear combat zone. The system shows good performance in terms of probability of connection even in the worst electromagnetic scenario and high traffic density. The most advanced technical solutions regarding hybrid DS/FH (direct sequence/frequency hopping) ECCM (electronic counter countermeasures) modulation and antenna coupling for the eight transceivers at the radio access point are discussed.<<ETX>>","PeriodicalId":394587,"journal":{"name":"MILCOM 92 Conference Record","volume":"46 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132390324","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 model preserves the low bit rate capabilities of the traditional LPC vocoder, but it features a more flexible parameterization of the LPC excitation signal. This allows the synthesizer to generate more realistic output speech, and it also increases the robustness of the coder to acoustic background noise. The vocoder has been implemented in a real-time system. Formal subjective testing of the coder confirms that it produces natural-sounding speech even in a difficult noise environment. In fact, diagnostic acceptability measure (DAM) test scores show that its performance is close to that of the 4800-b/s Department of Defense CELP (code excited linear prediction) coder.<<ETX>>","PeriodicalId":394587,"journal":{"name":"MILCOM 92 Conference Record","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128361882","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}

Of particular interest are the efficient memory shadowing technique used in the tone synthesis, the ability to vary the number of samples/symbol, the frequency offset correction method, and the modulation-derived synchronization (MDS) embedded synchronization technique which eliminates the need for any specific synchronization overheads.

Using Laguerre-series expansions for the statistics of the envelope of a sum of randomly phased sinusoids in Gaussian noise, analytic expressions for the probabilities of symbol events are obtained. These expressions can be accurately and rapidly evaluated compared to direct numerical integration. The general setup is applicable to the important case of varying and random amplitudes, which is related to the near-far problem in terrestrial radio networks.<<ETX>>","PeriodicalId":394587,"journal":{"name":"MILCOM 92 Conference Record","volume":"322 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134484261","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}
