第一次作业_基于分类算法的雷达状态识别
说明: 第一次作业_基于分类算法的雷达状态识别
对于本数据集中的雷达状态识别,数据降维前使用朴素贝叶斯、支持向量机、神经网络的分类算法对于识别的准确率无太大影响;数据降维后使用神经网络算法最优,支持向量机算法其次,朴素贝叶斯算法较差。此外,训练样本越多,分类准确率有小幅度提高。(First Operation Radar State Recognition Based on Classification Algorithms For radar state recognition in this data set, the classification algorithm of Naive Bayesian, Support Vector Machine and Neural Network before data dimension reduction has little effect on the accuracy of recognition; Neural Network algorithm is the best after data dimension reduction, Support Vector Machine algorithm is the second, Naive Bayesian algorithm is the worst. In addition, the more training samples, the smaller the classification accuracy.)

卷积编解码
说明: 使用Simulink(或m语言)仿真卷积编码,并用Viterbi译码的方法进行解码,其中的编码、译码全部是自己编写代码(m语言方式),不是调用Simulink(或m语言)的已有编码、译码函数。并在加性白高斯噪声信道中,画出比特信噪比与误码率的关系曲线。(Simulink (or M language) is used to simulate convolutional coding, and Viterbi decoding method is used to decode, in which the coding and decoding are all written by themselves (M language mode), rather than calling the existing coding and decoding functions of Simulink (or M language). In the additive white Gaussian noise channel, the relationship curve between bit SNR and BER is drawn.)
