Description: (书)现代通信系统使用MATLAB第一章-ALLIANCES is a recently proposed cooperative random access
protocol for wireless networks. In this paper we modify the
original model to include user location information. We also
derive pair-wise error probability (PEP) under Rayleigh flat
fading channel and a power-law attenuation environment.
Based on the PEP analysis we propose an optimal relay
selection scheme, which achieves significant throughput gains as
compared to the random relay selection scheme in the original
ALLIANCES. Platform: |

Description: 网络服务正在更新换代并且可扩展设备被设计成可提供在元计算环境中动态资源行为预测。这篇文章里，我们描述了预测产生的的设计和预测行为的细节。当预测方式为普通方式时，我们关注与他对TCP/IP端到端吞吐量能力的预测和在不同地点使用不同系统会带来的延迟量。因为在元计算软件的基础上网络预测需要计划的支持和质量服务保证的提高。-The Network Weather Service is a generalizable and extensible facility designed to provide dynamic resource performance forecasts
in metacomputing environments.In this paper,we outline its design and detail the predictive performance of the forecasts it generates.
While the forecasting methods are general,we focus on their ability to predict the TCP/IP end-to-end throughput and latency that is
attainable by an application using systems located at differentsites.Such network forecasts are needed both to support scheduling
(Bermanetal.,1996)and,by the metacomputing software infrastructure,to develop quality-of-service guarantees(DeFantietal.,to
appear Grimshawetal.,1994).

Description: 基于信道的历史信息来预测不同信道的未来可用时间可以帮助CR选择一个最佳信道进行信息传递。不同的预测准则应用到周期或是随机的开关模式中。一个CR可以学习以往不同信道的模式。我们提出一个简单的分类和学习方法去检测模式的类型和收集需要的信息用于智能信道的选择。MATLAB仿真结果显示提出的方案在随机信道的随机和周期模式中都有优越的表现。随着时间的变化，新到的切换次数减少到55 ，并且延迟时间也相应减少，而吞吐量却在提高。-Prediction of future availability times of different
channels based on history information helps a cognitive radio
(CR) to select the best channels for control and data
transmission. Different prediction rules apply to periodic and
stochastic ON-OFF patterns. A CR can learn the patterns in
different channels over time. We propose a simple classification
and learning method to detect the pattern type and to gather the
needed information for intelligent channel selection. Matlab
simulations show that the proposed method outperforms
opportunistic random channel selection both with stochastic and
periodic channel patterns. The amount of channel switches
needed over time reduces up to 55 , which reduces also the
delay and increases the throughput. Platform: |

Description: 利用matlab仿真了改进的二类选择重传HARQ机制的吞吐量与误比特率之间的关系。在仿真中对于编码和解码过程进行了简化：根据误比特率按概率模拟传输过程中码字的出错位数，在接收端只判断码字错误的位数是否在可纠错得范围之内。每发送一个码字，接收端根据出错位数信息检验其是否出错，没有出错则接收，否则要求重发，程序中利用alternate值交替发送信息码字和校验码字。当校验码字到来后，若校验码与原码组成的新码字能够纠错，则正确接收，否则要求重传。 -Retransmission the HARQ mechanism of throughput and bit error rate of the relationship between the use of matlab simulation improved second-class choice. In the simulation for the encoding and decoding process is simplified: digit of the code word of the error probability analog transmission process, according to the bit error rate of the receiving end only to determine the range of code word errors median whether error correction was. Each sending a code word, the information of the receiving end according to the error median test whether error, no error is received, or request retransmission, and the program using the alternate value alternately sent the information code word and the parity check code word. When the checksum word comes, if the new codeword able to check code with the original code error correction correctly received, otherwise require retransmission. Platform: |
