Soft combination of the observed energy values from different cognitive radio users is investigated. Square-law-combining (SLC) is theoretically proved to be nearly optimal in low signal-to-noise ratio (SNR) region, an usual scenario in the context of MIMO cognitive radio sensor networks. In particularly, the OFDM based MIMO cognitive radio sensor networks detect the primary user OFDM signal, where CR receiver is equipped with multiple antennas based energy detector. We observed significant impromvement in primary user detection with SLC based energy detection at the MIMO cognitive radio sensor networks.","PeriodicalId":342396,"journal":{"name":"2009 2nd IEEE International Conference on Computer Science and Information Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115025234","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}

Therefore, its design and development need to be validated by simulation. Particularly, we need to guarantee the reliability of the hardware-in-the-loop simulation (in short, HILS) system via Verification and Validation (V&V) during the Modeling and Simulation (M&S) for each sub-system. First, we analyze the common problem of most current V&V methods that they do not verify the model in this HILS system dynamically and automatically. Then, we present a dynamic V&V method based on HILS, and sequentially discuss the structure of the verifier, the verification algorithm and the validation criterion.

The data is extracted by reading the CompactFlash card to store as a data file. The recorded data file is analyzed by using the FFT to acquire the GPS satellites signals and the position is calculated by using the open source GPS positioning software.

Since ME models are able to flexibly utilize a wide variety of features, the sparse problem of training data is efficiently solved. Experiments show that the POS tagging error rate is reduced by 54.25% in close test and 40.56% in open test over the Hidden-Markov-Model-based baseline, and synchronously an accuracy of 98.01% in close test and 95.56%in open test are obtained.","PeriodicalId":342396,"journal":{"name":"2009 2nd IEEE International Conference on Computer Science and Information Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123015767","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}

Combining is done in order to improve the signal to noise ratio at the receiver. RAKE receiver attempts to collect the time-shifted versions of the original signal by providing a separate correlation receiver for each of the multipath signals. This can be done due to multipath components are practically uncorrelated from another when their relative propagation delay exceeds a chip period. This paper aims to present a system-on-chip (SoC) solution for RAKE receiver using a CORDIC hardware accelerator. The algorithm is implemented on Cyclone II FPGA device chipped on Altera DE2 board. The inbuilt NIOS II soft core processor of the FPGA device acts as the processor for processing applications. The CORDIC algorithm which computes the trigonometric functions is developed as a custom instruction for the NIOS II processor. This hardware accelerator has drastically improved the performance of the algorithm by about 70% when compared with the pure software implementation. This improvement in the performance is achieved at the cost of area. The performance of RAKE receiver is illustrated using bit error rate (BER) calculations. The RAKE receiver performance is examined and compared using maximal ratio and equal-gain combining techniques.","PeriodicalId":342396,"journal":{"name":"2009 2nd IEEE International Conference on Computer Science and Information Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114288462","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}

First, feature is generated from text and title, and then reduces the number of features by two feature selection techniques. Use these two types of features to give input to multi-class SVM.
