1. Introduction
In recent years, the GPU (Graphics Processing Unit), once usedonly for graphics processing, has been extended to general purposecomputing for its high computing power and bandwidth. Someearly researches adopted graphics programming languages such asCg, OpenGL to accelerate particle algorithms [1–3]. These worksshowed great potential of using GPU for scientific computing. Butcoding for scientific computing with these languages was difficultand the application fields were also limited. However, the developmentof general purpose computing on GPU has never stopped.NVIDIA Corporation released their parallel computing model calledCUDA (Compute Unified Device Architecture) for general purposecomputing in 2007 which provides an easy-to-use tool for scientificcomputing and is now widely used in many fields. Manyresearchers have used the tool in Computational Fluid Dynamics(CFD) and obtained remarkable results of performance increasing.Thibault et al. developed a Navier–Stokes solver for incompressibleflow on multi-GPU with a 2nd order accurate centraldifference scheme and achieved 100× speedup [4]. Bailey and his co-workers used CUDA for accelerating Lattice Boltzmann Methodon GPU and obtained remarkable performance enhancement [5].Frezzotti’s group adopted semi-regular methods to solve the Boltzmannequation on GPUs with high efficiency [6]. Ran et al. realizedthe GPU accelerated CESE method for 1D shock tube problems andachieved high acceleration ratios [7]. Brodtkorb et al. implementedshallow water simulations on GPUs and performed a detailed analysisof it [8]. Lutsyshyn presented a scheme for the parallelizationof quantum Monte Carlo method on GPU and the program wasbenchmarked on several models of NVIDIA GPUs [9].Implementing CFD method on GPU greatly depends on themesh type used. Compared with the structured counterpart, methodsbased on unstructured mesh cannot be efficiently acceleratedby GPU because the unstructured configuration leads to thenon-coalescent memory accessing on GPU. Some researchers madetheir efforts to overcome this difficulty. Corrigan et al. implementedan unstructured grid based Euler solver on GPU and obtaineda speedup of 33×’s [10]. Kampolis et al. accomplisheda GPU accelerated Navier–Stokes solver on unstructured grid inthe same year [11] and achieved a remarkable computing performanceincreasing. Waltz described the performance of CHICOMA,a 3D unstructured mesh compressible flow solver, on GPU and observedspeedup of 4–5× over single-CPU performance [12]. Laniet al. provided a GPU-enabled finite volume solver for ideal magnetohydrodynamicson unstructured grids within the COOLFluiD platform [13]. Almost all authors employed the renumberingtechnique to cope the problem of non-coalescent memory accessing,which has been discussed in detail in [14]. As demonstrated intheir works, with the renumbering technique, shared memory canbe introduced and therefore their codes’ performance is efficientlyimproved.

Theoretical and numerical characterization of a 40 Gbps long-haul multi-channel transmission system with dispersion compensation
سال انتشار : 2015
مقدمه انگلیسی مقاله:
1. Introduction
IntroductionA linear dispersion analysis on system performance can beused to predict the future needs of ultra-long haul and40 Gbps systems as it relates to dispersion compensation.The equations developed in Ref. [1] clearly show that theamount of residual dispersion at the end of a system thatone can accommodate is of the order of 1500 ps/nm for10 Gbps systems and only of the order 100 ps/nm for40 Gbps system. By considering an ultra-long haul transmissionat 10 Gbps system, it is seen that as we go to distancelonger than 600 km we need to start using dispersioncompensating devices in some of the in-line amplifiers. Assoon as transmission bit rates increase from 10 to 40 Gbpsand beyond, chromatic dispersion compensation becomes acritical issue on all kind of fibers, and the periodic dispersioncompensation for 40 Gbps terrestrial systems has beeninvestigated, with a new method being proposed on highlydispersed pulses to provide the evidence that the position ofdispersion compensating devices can be placed all at theend of the system [2]. Pizzinat et al. further analyzed thesetechniques using computer simulations [3].

1. Introduction
Comparing to traditional mobile communication terminals,larger display screen and higher data transmission rate are maincharacters of nowadays' smart devices, onto which hundreds ofapplications can be installed. To satisfy customer's expectations,newly released smart phones are coming with much higher pixelcamera for high quality pictures instead of regular sizes fromtraditional cameras. Thereby, due to limited battery energysupply, energy usage efficiency is required for high quality imagetransmission, especially under severely noisy channel.We apply Embedded Zero-tree Wavelet (EZW) for efficientimage compression. Firstly, Discrete Wavelet Transform (DWT)was used to extract the coefficient of an original image; after wavelet based decomposition, Pixel-Position information andPixel-Value information will be extracted form originalimage; after wavelet decomposition, image was extractedto large group of number ‘0’ which can be compressedlargely, followed by a couple number of none zero values.The large group of zeros contains Pixel-Position (PP) information,which is more important, the number of large valuecontaining Pixel-Value (PV) information, which is less importantfor image transmission [2]. In this paper, an adaptiveForward Error Correction (FEC) was applied on the importantpart of the image information, under bad communicationchannel, several mobile terminal as relays are used to set upa transmission network. For overcome the MIMO system'slimitation such as limited size and hardware complexity inwireless cellular system, Cooperative Diversity (CD) is used to‘extend’ the antenna number. Convolutional coding methodis also used for protect important part of image information(Pixel-Position), to achieve low BER and high data rate.Our contributions for this work are as follows:1. Unequally allocated energy to transmit important PixelPositioninformation and unimportant Pixel-Value information,due to the unequal importance of Pixel-Valueand Pixel-Position for image information containing.2. Proposed an adaptive Forward Error Correction (FEC)scheme, for achieving low BER under multipath fadingchannel and AWGN channel environment. Plus, evaluatedthe BER performance under complex channel conditions.3. Applied Cooperative Diversity with convolutional codingand multiple-relays in quality promised image transmissionchannel. Also, we analyzed the tunable coding ratioand relay number performance.
