First, we utilize the MoG(Mixture of Gaussian) method to model the background for segmenting the pixels of background. Than, we can calculate the foreground (moving object) pixels using difference between background model and current frame. In order to get more accurate foreground, we recommended a method which is combine HSV and gradient distribution for removing the shadows. For objects tracker, we used approach that incorporates the Kalman filter estimation with histogram information. The idea of proposed method is calculating the motion estimation with colour histogram corresponding to the detected objects that we want to track. Finally, we proved the performance of the proposed algorithm.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126753888","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}

Although several OBS testbeds have been reported, the BCP process time in core node is still not fast enough. In this article, a new high-speed OBS core node BCP processor based on FPGA is proposed. In the processor, a new valid wavelength scheduling algorithm is created. Not only does it have high bandwidth utilization in scheduling valid wavelength, but also the scheduling time is less. The performance is that a BCP just needs only 180ns for processing when system clock is 200MHz, about 50ns used to schedule valid wavelength and 130ns for other issues in core node.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127939486","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 proposed system can achieve twice bandwidth efficiency (BWE) than that of the BPSK modulated PC-OFDM system by sending a half time-domain BPSK-modulated PC-OFDM waveform. We propose two types of demodulation algorithm for this system, that is, orthogonality demodulation and M-algorithm demodulation. Orthogonality demodulation can recover the orthogonality between the subcarriers with 3 dB BER performance deterioration. The M-algorithm demodulation can realize a BER performance improvement with a moderate computational complexity.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134182349","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}

Besides being used as spreading sequences, they can also be used for channel estimation, synchronization, reduction of peak-to-average power ratio of symbols, preamble design, sequence design, Target detection and so on. A recursive construction of complementary sequences based on orthogonal matrix and permutation matrix is proposed, which increases the number of complementary sequences in the set by increasing the number of their sub-sequences with the same sequences' length. Then the anti-interference performance of multi-carrier CDMA (MCCDMA) system based on complementary sequences is simulated, and the obtained results show that it has better anti-interference ability than traditional CDMA system.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115907081","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 our previous work, novel ordering schemes have been proposed to reduce the computational complexities and/or memory requirements of various maximum likelihood (ML) MIMO detectors. In this paper, we incorporate our ordering schemes with the K-Best detector, which is a near-ML detector and is particularly suitable for hardware implementation. Our simulation results show that our ordering schemes greatly improve the reliability of the K-Best detector. Given a fixed detection error rate, our ordering schemes either result in SNR gains or enable the usage of even smaller K, thereby leading to small area and power consumption and higher throughput for their hardware implementations.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124738166","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 concept of Multi-User Reusing-One-Slot (MUROS) is promising to resolve this problem with negligible impact on handsets as well as to networks. In this paper, we compared the link-level and system-level performance of two main solutions of MUROS, Orthogonal Sub-Channel (OSC) and Co-Traffic Channel (Co-TCH). The theoretical analysis and the simulation results based on OPNET Modeler is shown, which indicates that with the proper application, OSC can significantly improve the capacity of GSM/EDGE networks without degrading speech quality, while Co-TCH has to employ enhanced interference canceling techniques, such as mobile station receive diversity (MSRD).","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130558250","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}
