The ASIP architecture can be configured allowing re-use between both modes. Key in the architecture is parallelization, which is exploited in the SIMD engine. Binary LDPC codes intrinsically enables parallelization through layered decoding while in the non-binary case different trade-offs can be made. The implementation choice was made base on minimal memory requirement and computational effort. For a combination of supporting binary LDPC present within WLAN and WiMAX standard with non-binary GF(8) LDPC codes, a total area of 5.4 sqmm in commercial 65nm technology would be required. This size can be reduced towards 3.4 sqmm if only half of the non-binary decoding throughput is required.","PeriodicalId":344975,"journal":{"name":"2010 17th IEEE Symposium on Communications and Vehicular Technology in the Benelux (SCVT2010)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132603769","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 growth is further asserted by the latest breakthrough boosting the capacity of copper access such as Vectoring and Phantom mode [2]. While most of the state of the art power efficiency improvement strategies for communication systems focuses on the optimization of one specific building block at a time, we take another approach based on the deployment practices and how different access network architectures can improve the energy consumption. To achieve substantial energy savings, we look at the complete broadband access network and its supporting functions. Not only the access network equipment such as the DSL Access Multiplexer (DSLAM) is considered but also the supporting functions which are required to make sure that the equipment can operate. It will be shown in this paper that up to 50 % of the energy consumption in the distributed deployment can be saved compared to the centralized architecture.","PeriodicalId":344975,"journal":{"name":"2010 17th IEEE Symposium on Communications and Vehicular Technology in the Benelux (SCVT2010)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125063519","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}

Feedback mechanisms have been proposed, according to which the clients notify the server of their needs directly or indirectly. This feedback is then processed at the server, producing the items' access probability distribution function estimate. Based on the principle of maximum uncertainty, a novel, extremely lightweight adaptation scheme algorithm is proposed. Requiring trivial input, this algorithm is shown to estimate almost perfectly the real probability distribution, while alleviating synchronization issues of related approaches and minimizing the processing needs at the server side.","PeriodicalId":344975,"journal":{"name":"2010 17th IEEE Symposium on Communications and Vehicular Technology in the Benelux (SCVT2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114265870","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}

Even if AAA is seen as a solution for interference avoidance, wrong implementation of AAA in ad hoc networks can lead to a general deterioration of network performance. Forward interference avoidance (FIA) concept has been proposed as one solution to this problem. The FIA concept allows to foresee, before the start of transmission, if a communication, intended by a node in an ad hoc network, will be successful and if this node could interfere with other communications. It does so by evaluating traffic demands by using two threshold values. In this paper, we explain how to estimate the two threshold values as they are vital to its correct functioning. We show how the values may be chosen depending on network requirements by using a cumulative distribution function CDF and proof its correctness by optimizing with linear programming.","PeriodicalId":344975,"journal":{"name":"2010 17th IEEE Symposium on Communications and Vehicular Technology in the Benelux (SCVT2010)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114629755","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}

Transmission over the wireless channels is prone to noise and interference which causes the reception of erroneous packets at the receiving node. Automatic Repeat Request (ARQ) techniques are usually used in WSNs to tackle erroneous transmission, but they become inefficient (with respect to energy and delay) in harsh environments. To reduce the number of retransmission for lossy channels, Error Correcting Codes (ECC) are commonly used. The use of ECC comes with increased processor power and delay at the sensor nodes for encoding and decoding the packets. In this work we present an ECC technique for sensor networks based on Turbo Codes. A low complexity turbo encoder is deployed at the source nodes, while the iterative decoding process is shifted to the Base Station. The forwarding nodes contribute by executing error monitoring and correcting.

In this paper we propose a new approach for interference suppression in UWB. This approach combines analog suppression with flexible digital suppression in a UWB receiver. To suppress strong interference, analog and digital band reject filtering is combined with tone nulling. For weak interference only tone nulling is applied. We use system simulations to maximize the interference robustness of a UWB receiver for practically relevant interference models, while minimizing the use of the band reject filters. We show that our interference suppression scheme improves the interference tolerance by at least 35 dB.","PeriodicalId":344975,"journal":{"name":"2010 17th IEEE Symposium on Communications and Vehicular Technology in the Benelux (SCVT2010)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127755406","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}
