The L-band Digital Aeronautical Communication System (L-DACS) is the part of the future system that will be operating in a part of the aeronautical L-band (960-1164 MHz), already occupied by a large number of radio-frequency legacy systems. This paper aims at studying the L-DACS impact on a legacy system, the Distance Measuring Equipment (DME), under two critical situations. Such topics are fundamental in aeronautics, as any communication or radionavigation dysfunction may endanger flight and passengers security. Some obtained results will be used for the L-DACS standardization and its specifications finalization. For the first scenario (air-to-air scenario), we propose a deterministic algorithm to compute the interference level in the frequency domain. Since this seems to be insufficient for the second scenario (co-site scenario), we develop a time-frequency approach to analyze the interference using an aeronautical RFC test-bed that we implemented at Supelec.","PeriodicalId":262730,"journal":{"name":"2012 IEEE First AESS European Conference on Satellite Telecommunications (ESTEL)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127228786","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 dual redundant data bus will provide exchange of information in almost all operative conditions and connect all the electronic peripherals, supporting the data exchange speed required by the different sub-systems composing the satellite. The proposed architecture uses differential bus with galvanic isolation among all the connected modules in order to have fault tolerance, good signal integrity and to connect as many tiles in series or in parallel. The proposed structure has been tested in almost all possible fault conditions and the simulation and actual results show reliable transmission and reception of signal from one module to the other even under different types of fault conditions. System stability is guaranteed by the proposed characteristic of each subsystem in such a way that any number of modules can be connected to the communication bus without impairing overall performance and stability. This work presents the bus interface circuit located between the processor and the communication channel and also the fault tolerance analysis with different possible types of faults.","PeriodicalId":262730,"journal":{"name":"2012 IEEE First AESS European Conference on Satellite Telecommunications (ESTEL)","volume":"45 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125898815","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 queue-based schemes, the controller's objective is to drive the buffer queue length to an appropriate reference queue length, and the efficiency of the control strictly depends on the choice of its reference value. In latest approaches, solutions to adaptively modify the target reference queue length based on a set of network information have been proposed; nevertheless, in such approaches, the satellite terminals should base their control strategies on information which are not available to them, according to the communication standards of state-of-the-art technologies, such as DVB-RCS. The novelty of the presented algorithm is that it overcomes this limit by dynamically changing the reference queue length, based on information actually broadcast to the network terminals; the algorithm is at same time simple and effective, and is based on a game-theoretic approach which benefits of recent advances in congestion pricing theory. The effectiveness of the proposed approach is supported by Opnet® simulations as well as by considerations about the real implementability of the solution.","PeriodicalId":262730,"journal":{"name":"2012 IEEE First AESS European Conference on Satellite Telecommunications (ESTEL)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115984779","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}
