However, the main ideas of SOA are very different from the needs for a C4I2SR. The paper provides a mapping of the ideas of SOA to the needs of C4I2SR. Especially, SOA Business Processes seem useful. The paper gives architectural views on a hybrid SOA system that may be suitable for C4I2SR. Specific problems of migrating present C4I2SR systems to SOA, such as legacy systems and service registry, are also addressed.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116850560","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 space-time coding techniques are still preferred in communication systems because of the very simple transmit coding rule and of the relative reduced complexity of the maximum likelihood (ML) receivers with respect to other coding methods (e.g., space-time trellis codes) or other MIMO (Multiple Input Multiple Output) algorithms (e.g., spatial multiplexing). One of the drawbacks when using space-time block codes is the increase in complexity at the ML receiver when increasing the number of transmit antennas and the number of constellation points. This paper deals with this issue and introduces a decoding algorithm applicable only for orthogonal space-time block codes. We show that this decoding algorithm reduces the search space dimension of a regular ML receiver, leading to significant complexity reduction for quadrature amplitude modulation (QAM) constellations. The algorithm is then extended to an arbitrary number of receive antennas, increasing the spatial diversity order.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116924666","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}
