利用贝叶斯原理估计混合logit模型的参数，现代信号处理中谱估计在matlab中的使用，最大似然（ML）准则和最大后验概率（MAP）准则，是学习PCA特征提取的很好的学习资料，本程序的性能已经达到较高水平，对HARQ系统的吞吐量分析。- Bayesian parameter estimation principle mixed logit model, Modern signal processing used in the spectral estimation in matlab, Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion, Is a good learning materials to learn PCA feature extraction, The performance of the program has reached a high level, HARQ throughput analysis of the system.
