《MATLAB程序设计教程》一书的随书源代码("MATLAB Programming Guide," a book of the source code along with book)

matlab课件很有用的,对matlab学习很有帮助,希望采纳谢谢(it s very useful)

在无线通信体系中,由于开放的通信信道条件,卫星通信系统中通信链路容易受到平均大气条件的影响,尤其是采用Ka波段的高频信号的系统,容易受到降雨造成的雨衰影响,严重影响了系统的有效性和可靠性。(In a wireless communication system, the communication channel open, average atmospheric conditions vulnerable to the communication link in satellite communication system, especially the system of high frequency signal using Ka band, vulnerable to the influence of rain attenuation caused by rainfall, seriously affect the validity and reliability of the system. In digital systems, channel coding is often used to improve reliability, while modulation is used to ensure effectiveness. Low order modulation and large redundancy coding are adopted to improve the reliability.)

本代码的方法是借助旋转不变技术估计信号参数(Estimation of Signal Parameters via Rotational Invariance Techniques)，现已成为谐波恢复（即正弦波个数及频率估计）的一种主要特征分解法。(This code is to help the estimated ESPRIT signal parameters (Estimation of Signal Parameters via Rotational Invariance Techniques), has now become the harmonic retrieval (that is, the number and frequency sine wave estimated) of one of the main characteristics of decomposition.)
