试说明卷积编解码的工作原理。 请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编解码全部自己编写代码(S-Function方式)，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。 (Description Convolutional codec test works. Please use Simulink simulation of convolutional coding and Viterbi decoding method used to decode, which codec to prepare all their own code (S-Function mode), in the AWGN channel, drawn-noise ratio and bit error rate curve.)

数字图像处理MATLAB源码(digital image processing MATLAB source)

Implementation of the Murty algorithm to obtain the best K assignments. Includes the implementation of the Jonker-Volgenant algorithm. Usual applications are multiple target tracking algorithms, Joint Probabilistic Data Association (JPDA), Multiple Hypothesis Tracking (MHT), Global Nearest Neighbours (GNN), etc. Based on the original code by Jonker-Volgenant, and the Murty Matlab implementation by Eric Trautmann Can be used both from Java or Matlab. Time for a 100x100 assignment problem, with k=20: • Matlab implementation: 54.5 sec • Java implementation: 1 sec
