功率谱估计的应用范围很广,在各学科和应用领域中受到了极大的重视。在《现代信号处理》课程中讲述了经典谱估计和现代谱估计这两大类谱估计方法;经典谱估计是基于傅立叶变换的,虽然具有运算效率高的优点,但是频谱分辨率低同时旁瓣泄漏严重,对长序列有着良好的估计。为了克服经典谱估计的缺点,人们开展了对现代谱估计方法的研究。现代谱估计是以随机过程的参数模型为基础的,有最大似然估计法、最大熵法、AR模型法、预测滤波器法。现代谱估计对短序列的估计精度高,同经典谱估计互为补充。在认真学习了现 代谱估计方法后,我选择了

卷积码的译码方法主要有两种:代数译码和概率译码。代数译码是根据卷积码的本身编码结构进行译码,译码时不考虑信道的统计特性。概率译码在计算时要考虑信道的统计特性。典型的算法如:最大似然译码、Viterbi译码、-Convolutional Decoding by two major ways : Decoding algebra, probability and decoding. Decoding is based on algebraic Convolutional Codes itself c
