It has been showed to achieve near Maximum Likelihood (ML) performance with low complexity. However, the complexity of conventional SD algorithm is high under the specific environment. The performance and the computation complexity of SD algorithm is highly dependent on the initial choice of sphere radius. Thus, it is important to design a proper initial radius scheme for SD which improve the performance and reduce the computation complexity. In this paper, we propose a novel scheme base on the knowledge of statistical probability and the constellation energy to design a new initial radius scheme. The performance and algorithmic efficiency of this scheme are increased by application of a factor constellation energy E. The simulation results show under the low signal-to-noise ratio (SNR) condition. The proposed scheme can achieve the aim that save more operation time than the conventional SD algorithm. At the same time, the performance gap compared to conventional SD algorithm can be restricted to a certain level.","PeriodicalId":398930,"journal":{"name":"2017 IEEE 2nd International Conference on Opto-Electronic Information Processing (ICOIP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132893336","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 impact of fiber effective core area to Raman amplification gain, Kerr nonlinear signal distortion, Raman amplifier induced noise and optical signal to noise ratio are analytically investigated. Performance characteristics of various transmission data rate of differential phase modulated signal over 390 Km transmission distance of different effective core area fibers are examined.

According to recently reported news, an area with 650 Sv/h radiation intensity has been confirmed outside of a containment vessel at the Fukushima Daiichi nuclear power plant. For uses under such extremely high radiation environments, high-speed scrubbing operations must be applied for FPGAs. A high-speed optical scrubbing method that can be used on optically reconfigurable gate arrays has been proposed in recent reports of the literature. Such optically reconfigurable gate arrays using optical high-speed scrubbing can be used in environments with intense radiation. In addition, to increase the optical scrubbing operation speed, this paper demonstrates a high-speed optical scrubbing method with a simpler sequence for use on an optically reconfigurable gate array. The 50 ns period high-speed scrubbing operation could be confirmed on the fabricated optically reconfigurable gate array VLSI.","PeriodicalId":398930,"journal":{"name":"2017 IEEE 2nd International Conference on Opto-Electronic Information Processing (ICOIP)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131928757","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 new distributed algorithm divides whole network into some globally rigid subset based on rigid graph theory, in which nodes have close spatial correlation, less hop and alike path direction with all of other nodes in the same subset, and it reduces the error by shortest path. And afterwards, some boundary nodes close to other subsets is chosen as framework with anchor nodes to locate the whole network. Finally, homogeneous coordinate system is used to make the geometric change.

It requires high network throughput as well as robustness against Multiuser Interference (MUI), multipath fading and other channel effects. This is achieved by using the hybrid Direct Sequence Time Hopped CDMA (DS-TH CDMA) systems. In this paper, a novel usage of State-Space Recursive Least Squares with Adaptive Memory (SSRLSWAM) with non-coherent detection is proposed for adaptive equalization of DS-TH CDMA system. The proposed algorithm is able to mitigate multipath fading effects through adaptive equalization by effectively initializing the SSRLSWAM and tuning its forgetting factor. The choice to use non-coherent detection is made because of the fact that non-coherent detectors do not utilize the phase information at the receiver side, resulting in lowering computational complexity. The BER performance of the proposed algorithm is compared with the correlating detector and Minimum Mean Square Error (MMSE) detector. It is shown that SSRLSWAM results in BER performance better than both the correlating and MMSE.","PeriodicalId":398930,"journal":{"name":"2017 IEEE 2nd International Conference on Opto-Electronic Information Processing (ICOIP)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116199299","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}

We develop the passivity-based coordination framework to enhance position as well as force tracking in the presence of different initial conditions, environmental forces and unknown parameters like friction coefficient. To remedy these difficulties, a nonlinear sliding mode controller is proposed to approximate the nonlinearity in master and slave robots dynamics and enhance both position and force tracking. The boundedness of master- slave tracking errors and the stability of the teleoperation system are proved by Lyapunov theory. Numerical simulations show that proposed controller position and force tracking performances are superior to conventional coordination controller tracking performances.","PeriodicalId":398930,"journal":{"name":"2017 IEEE 2nd International Conference on Opto-Electronic Information Processing (ICOIP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125513699","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}
