Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK. Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve. The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one) of the information-bits Weight Enumerating Function (WEF) using A simulation of the convolutional encoder. Once the WEF is estimated, the analytic formula for the BER is used.(Computes BER v EbNo curve for convolutional encoding/soft decision Viterbi decoding scheme assuming BPSK.

统计信号处理，参数估计的方法，包括：最大似然，最小二乘方法，Monte_Carlo(Statistical signal processing, parameter estimation methods, including: maximum likelihood, least squares method, Monte_Carlo)

working of the fifth generation intelligent radio that is Cognitive Radio (CR) system which works on predictive data rate and propose ANFIS based learning scheme to introduce intelligence in it. The testing data set is taken from training set. Validation data set is unseen data. RMSE and prediction accuracy are used as performance index. Two gaussian membership functions are taken for each input. Error goal was set for .001.Training was for 300 epochs. It is seen prediction accuracy was 91 percentages in testing case and 89 in validation. RMSE difference between validation and testing case very small.

一篇文章，利用DWG格式地形图建立城DEM， 利用VBA 语言编程,提取离散高程点及其高程注记,并将高程点与高程注记匹配存储 对等高线进行有效的离散化,提取等高线的高程信息.而后将提取的高程数据在ArcGIS以三维可视化的人机交互的方式剔除粗差,最后生成DEM.(an article, the use of topographical maps DWG format established City DEM using VBA programming language. Elevation extract discrete points and elevation Note, and elevation and elevation point Note matching storage right contour effective discrete, Extracting the elevation contour information. and after extraction of elevation data to the ArcGIS 3D visualization of Human-Computer Interaction way removed gross error, the last generation DEM.)
