However, Simulation-Based Verification (SBV) which comes under dynamic verification approach can handle these complex systems. Among the various modern SBV approaches, Universal Verification Methodology (UVM) provides well established and flexible solution for complex system design verification. Flexibility of UVM lies in the fact that the verification environment developed using UVM consists of reusable components and is supported by tools of all major vendors of the industry. UVM provides a complete framework to achieve coverage driven verification that includes automatic test generation, self-checking testbenches and coverage metrics [1]. The self-checking capability provided by UVM is not very well defined and, hence, forces verification engineer to develop complex checking mechanism even for very small designs and also provides less resources for thorough checking of complex designs. In this paper, we will discuss implementation details of different kind of checking mechanisms that can be used along with UVM based verification environment to improve its capability of functional checking, protocol checking and reaching hidden bugs of the Design Under Verification (DUV).","PeriodicalId":202893,"journal":{"name":"2015 International Conference on Advances in Computer Engineering and Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125113692","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}

For the purpose of spectrum pooling, OFDMA based multi-carrier techniques such as NC-OFDM offers a good choice due to flexibility in deactivating the subcarriers occupied by primary licensed users to avoid interference, but suffer from high PAPR, not desirable particularly at the user equipment (UE) end. Single Carrier FDMA with localized and interleaved mapping gives lower PAPR at the UE end in the uplink. While Interleaved SC-FDMA has least PAPR along with higher frequency diversity, it requires the free subcarriers to be in a certain pattern, i.e. equi-spaced which is not guaranteed in spectrum pooling due to the fact that the total number of free subcarriers and their locations might change continuously in a dynamic spectrum access network. In this paper, we propose a spectrum allocation algorithm that gives an optimum DFT size and the bandwidth spreading factor to decide the number of users that can be allocated depending on specified required spectral efficiency so that the UE can employ Interleaved SC-FDMA to improve PAPR performance at its transmitter. The simulation results show that the algorithm aims to find an optimum DFT size that balances the required spectral efficiency with significantly reduced PAPR at the UE end as compared to NC-OFDMA and localized SC-FDMA.","PeriodicalId":202893,"journal":{"name":"2015 International Conference on Advances in Computer Engineering and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132492069","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}

Despite great strides in the field, the domain of context driven text classification provides fresh opportunities to develop more efficient context oriented techniques with refined metrics. In this paper, we propose a novel approach to categorize text documents using a dual lexical chaining technique. The algorithm first prepares a cohesive category-keyword matrix by feeding category names into the WordNet and Wikipedia ontology, extracting lexically and semantically related keywords from them and then adding to the keywords by employing a keyword enrichment process. Next, the WordNet is referred again to find the degree of lexical cohesiveness between the tokens of a document. Terms that are strongly related are woven together into two separate lexical chains; one for their noun senses and another for their verb senses, that represent the feature set for the document. This segregation enables a better expression of word cohesiveness as concept terms and action terms are treated distinctively. We propose a new metric to calculate the strength of a lexical chain. It includes a statistical part given by Term Frequency-Inverse Document Frequency-Relative Category Frequency (TF-IDF-RCF) which itself is an improvement upon the conventional TF-IDF measure. The chain's contextual strength is determined by the degree of its lexical matching with the category-keyword matrix as well as by the relative positions of its constituent terms. Results indicate the efficacy of our approach. We obtained an average accuracy of 90% on 6 categories derived from the 20 News Group and the Reuters corpora. Lexical chaining has been applied successfully to text summarization. Our results indicate a positive direction towards its usefulness for text classification.","PeriodicalId":202893,"journal":{"name":"2015 International Conference on Advances in Computer Engineering and Applications","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134590521","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}
