Webb摘 要 本次课程设计为基于matlab的bpsk原理电路仿真。本次课设着重介绍了算法的实现,并采用matlab程序仿真测试了bpsk过程中单极性不归零编码、脉冲成形、psk调制、信号通过awgn信道、载波恢复、解调、解码等过程。 关键词bpsk;2psk;matlab;数字频带通信; 目 录 绪论 数字信号传输方式分为数字带通 ... WebbDescription. Y = fft (X) computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm. If X is a vector, then fft (X) returns the Fourier transform of the vector. If X is a matrix, then fft (X) treats the columns of X as vectors and returns the Fourier transform of each column.

Webb10 okt. 2024 · 在这里我们主要自定义了以下几个函数:SNR,plotspec,wiener分别为信噪比计算函数,频谱分析函数,维纳滤波函数。其中wiener函数是系统的主要函数,通过这个函数,我们就可以完成语音信号的增强处理。然后通过plotspec进行信号的频谱分析。 http://www.idata8.com/rpackage/x12/plotSeasFac-methods.html

Webb逻辑回归又叫logistic回归分析,是一种广义的线性回归分析模型。. 线性回归要求因变量必须是连续性的数据变量,逻辑回归要求因变量必须是分类变量,可以是二分类或者多分类 (多分类都可以归结到二分类问题),逻辑回归的输出是0~1之间的概率。. 比如要分析 ...
