F. P. Pongsapan, Hendrawan
Today's communication and entertainment World videos play a very important role in. Many services are being developed based on the concept of video like video streaming, video calling etc. The increase in demand for such services made the service providers evince interest in investigating, monitoring and maintaining the quality that they provide for such services. In order to improve the quality for delivering video services, video quality evaluation is necessary. For this purpose many tools to evaluate the quality of a video have been designed. In this research we use several parameter to evaluate video transmission on the LTE network, which is run on open source network simulator called Network Simulator 3. We have evaluated a set of videos using this simulator to examine the performance of HEVC video compression on LTE network and calculate to know how this parameter impact the video quality if the video sent via LTE network by determine its PSNR.
视频在当今世界的传播和娱乐中扮演着非常重要的角色。许多基于视频概念的服务正在被开发,比如视频流、视频通话等。对这类服务需求的增加使服务提供者表示有兴趣调查、监测和维持它们提供的这类服务的质量。为了提高视频业务的传输质量,需要对视频质量进行评估。为此,人们设计了许多评估视频质量的工具。在本研究中,我们使用几个参数来评估LTE网络上的视频传输,该网络在开源网络模拟器network simulator 3上运行。我们使用该模拟器评估了一组视频,以检查LTE网络上HEVC视频压缩的性能,并通过确定其PSNR来计算该参数如何影响通过LTE网络发送的视频质量。

Cell capacity prediction with traffic load effect for soft frequency reuse (SFR) technique in LTE — A network LTE - A网络软频率复用(SFR)技术中基于业务负载效应的小区容量预测
H. Hidayat, Al Kautsar Permana, I. Ridwany, Iskandar
The next generation OFDMA-based cellular network that targeted high spectrum efficiency requires the frequency reuse system as one of the solutions, such as a deployment needs a good planning as well. In this paper, an analysis of soft frequency reuse (SFR) performance under various traffic loads is another important task, in case planning a good cellular network based on cell capacity is something considered. We predict it in LTE — A Network which offers higher data rate than LTE Network. The result shows that SFR can mitigate the inter-cell interference by providing higher troughput for cell-edge users. Also, in order to achieve better performance of traffic load effect, cell radius is varied. The result indicates that troughput maximum is obtained when cell radius is 700 m.

Traveling salesman problem using multi-element genetic algorithm 基于多元素遗传算法的旅行商问题
I. B. K. Widiartha, Sri Endang Anjarwani, Fitri Bimantoro
Travelling Salesman Problem (TSP) has been a favorite problem to solve. The idea is to search an optimal route between location. TSP always uses a distance as a cost, although there are other costed elements except for the distance. We found out that obstacle was another cost besides distance in TSP. It increases the elements to be evaluated. We need an approach to solve multi-elements TSP. Multi-Element Genetic Algorithm (ME-GA) was used to solve the NP-hard problem. It was proved that ME-GA provided a solution for a multi-element problem. In the crossover process, we use Partial Map Crossover (PMX), showing that PMX is overwhelmed Oder Crossover (OX) and Cycle Crossover (CX) methods. We formulate a multi-elements fitness function by three elements: distance, fixed obstacle, and non-fixed obstacles. The elements have a proportion of the fitness function; we give 70% for the distance, 20% for the fixed obstacle and 10% for the non-fixed obstacles. The results show that the distance of the location increased but we can minimize the number of obstacles. Compared to if only distance to evaluation, we find the shortest distance between the location, but we cannot decrease the number of obstacles.
旅行商问题(TSP)一直是人们最喜欢解决的问题。其思想是寻找一个最优路线之间的位置。TSP总是使用距离作为成本,尽管除了距离之外还有其他成本元素。我们发现障碍是TSP中除了距离之外的另一个成本。它增加了要计算的元素。我们需要一种解决多元素TSP的方法。采用多元素遗传算法(ME-GA)求解np困难问题。证明了该算法为多单元问题提供了一种求解方法。在交叉过程中,我们使用了部分映射交叉(PMX),表明PMX优于有序交叉(OX)和循环交叉(CX)方法。我们用距离、固定障碍和非固定障碍三个要素构造了一个多元素适应度函数。各元素具有一定比例的适应度函数;距离70%,固定障碍20%,非固定障碍10%。结果表明,定位距离增加了,但障碍物的数量可以最小化。相比于只评估距离,我们找到了距离最短的位置,但我们不能减少障碍物的数量。

Velocity and acceleration analysis of land deformation: Case study on Kelok Sembilan bridge 陆地变形的速度和加速度分析:以克洛克森美兰大桥为例
P. Razi, J. Sumantyo, Daniele Perssin, A. Munir
Characteristic analysis of land deformation in some area is very helpful for mapping and preventing the impact of landslide. Here, Persistent Scatterer Interferometric (PSI) Synthetic Aperture Radar (SAR) technique has been applied on 13 scenes of ascending track acquired by Advanced Land Observation Satellite Phased Array L-band Synthetic Aperture Radar (ALOS PALSAR) from July 2007 until November 2010 for characteristic analysis of the landslide. The technique is employed to identify and measure land deformation on the earth surface. The PSI technique has good accuracy in overcoming temporal and geometric decorrelation compared to conventional interferometric SAR technique. The result for analyzing landslide deformed area on Kelok Sembilan bridge has been identified. In addition, time series of landslide deformation history were used for calculating the past velocity and acceleration of landslide as well as for estimating for the future.
对某地区的地表变形特征进行分析,对测绘和防治滑坡影响具有重要意义。本文对2007年7月至2010年11月由先进陆地观测卫星相控阵l波段合成孔径雷达(ALOS PALSAR)获取的13个上升轨迹场景进行了持续散射体干涉合成孔径雷达(PSI)技术的应用,对滑坡特征进行了分析。该技术被用于识别和测量地表的陆地变形。与传统干涉SAR技术相比,PSI技术在克服时间和几何去相关方面具有较好的精度。对克洛克森美兰大桥滑坡变形区进行了分析,得出了分析结果。此外,还利用滑坡变形历史时间序列计算了滑坡过去的速度和加速度,并对未来进行了预测。

Disaster mitigation is defined as activities to reduce the loss of life and assets. The information technology (IT) grows rapidly and brings benefits and values to human such as automating processes, gaining efficiency and effectivity, helping human in solving problems, and taking decision. In this research, we propose the used of IT such as mobile technology, geofencing technique, and also communication technology such as the concept of smartphone ad hoc networks (SPANs), and Optimized Link State Routing (OLSR) Protocol to ensure the information about disaster mitigation in the disaster-prone area spread widely. This finding aims to enhance local community and tourists awareness, spread the whole information about disaster mitigation, and help the government to evaluate, direct, and monitor the disaster mitigation, and accommodate less delayed communication while the disaster occurs.

Iskandar, R. Hakim, M. E. Ernawan
In this paper, we conducted a comparative analysis of the scheduling methods taking a case study in urban, sub urban, and rural environment. The rapid changing of data and information has encouraged the growth of LTE technology which has capable of meeting the needs of data transfer. With scheduling analysis we can determine the best schemes in each type of radio environment such as urban, suburban and rural which produce maximum throughput and the most efficient planning. From this research, proportional fair scheduling algorithms in general is the best algorithm with greatest throughput output for each area, which is urban (max 1154 kbps), suburban (max 2291kbps) and rural (max 3888 kbps). In urban areas proportional fair had better throughput up to 113% in low PDSCH level (<20 dB) compared to Round robin and Maximum C/I scenario.

Non-parametric phase tracking in demodulation and decoding of QAM signals affected by phase noise 受相位噪声影响的QAM信号解调解码中的非参数相位跟踪
A. Spalvieri
Digital optical and radio transmission systems based on high order modulations can be severely impaired by phase noise affecting the local oscillators used for up-conversion and down-conversion. Pilot symbols can be of help in mitigating the impact of phase noise. This paper proposes a pilot-aided demodulation scheme where phase noise tracking is performed by a trellis-based algorithm. The benefits in terms of achievable information rate and bit error rate compared to adversary schemes are demonstrated by computer simulations for strong phase noise with coded 4096-QAM.
