Historically, telecom regulators assigned fixed spectrum bands to the licensee wireless network operators, this spectrum management approach is guarantee interference free environment, except of some configurations faults or illegal usage. However, with the increasing demand for more bandwidth in the finite radio spectrum, the concept of secondary operator's was emerged, but with emphases to not influence licensed operators. Consequently, Cognitive Radio Networks (CRN) architecture enters the market as an intelligent solution to these issues, with concentration on the spectrum sensing procedures to achieve the regulatory constraint. The most successful sensing algorithms is those applying cooperation and scheduling to have better scanning information, however those algorithms are developed base on the primary network activities which is good in terms of reducing the expected interference, but it lay more computational loads on the CRN. In this paper, a novel sensing scheduler algorithm is proposed, the idea is to utilize the CRN by fairly distribute the sensing task among the sensors, then utilizing the radio spectrum shared with the primary networks.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126770119","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}

Software processes are improved by implementing software process standards. These standards are often called software process improvement frameworks or standards. Software process improvement is necessary to increase the efficiency and productivity of software companies and enhance the final software products. However, most of the Sudanese software companies do not follow any software process improvement standards. For this reason, normally these companies produce the software without high quality. Furthermore, the low quality may be the cause of some problems such as unreliable software and high maintenance. Some of the Sudanese software organizations were visited, to interview software experts and observe how these organizations can improve their software process. Furthermore, the results of these interviews have been used to design a questionnaire in order to show the relationship between Sudanese software organizations and software process improvement standards. This study has identified the problems faced by these organizations during the implementation of software process improvement standards and shows the ability of these organizations to implement the software process improvement standards. Moreover, this work can be used as a first step towards to produce software process improvement standard for the Sudanese software industry.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"103 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114188012","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}

However, in this paper a digital filter is proposed to be designed as a multifunction processor, achieving several sorts of signal processing within the same module. Processing is easily done in the baseband rather than in passband, for a moderately slow DSP processor. Hence, a lowpass filter will perform the task of rejection of the out-of-band interference. Higher SNR can be obtained to enhance the detection of targets inside noise if that filter is matched to the expected radar signal, even if it caused signal distortion. Doppler processing makes use of digital filters to cancel signals from fixed and slow targets. The proposed filter would be designed as an adaptive filter to follow interference and clutter changes, and eliminate blindness to some moving radar targets that arise in digital Doppler processing due to aliasing caused by targets of higher speeds. Matlab simulations are made to validate the idea and observe features and limitations of the proposed adaptive filter. Adaptive filter that is based on the least-mean-square algorithm is designed to achieve the best outcome.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125556119","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 basic idea of the new algorithm is to define a pattern for each word in a static dictionary by replacing all or most of the characters in the words of the dictionary by the most frequently used character in any text file. The proposed algorithm transforms any text file into another encrypted file with a size almost the same as that of the original text file but with different statistical properties. The new transformation method has been designed, implemented, and tested using Gutenburg Corpus. Generally, the output result has shown different levels of enhancements on different common standard data compression tools such as Arithmetic, Huffman, Bzip2, Gzip and WinZip. The compression performance of all common compression tools has been enhanced especially when the patterns of the transformed words passed through costless running length encoding (RLE) algorithm. On using Bzip2, the resultant output files produced about 76.75% as compression ratio with 1.88 as average code length. The final result is very promising and it could be enhanced more in case of applying dynamic dictionary-based text transformation technique.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130889254","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}
