47651515CDMA
选取CDMA通信系统中的接入信道部分进行仿真与分析。首先,通过学习相应的理论知识,熟悉接入信道实现的过程,对每一步的原理有了较深的理解,同时,也对MATALB软件进行熟悉和了解,对MATLAB软件中的SIMULINK部分及其内部的CDMA模块用法和参数设置进行熟悉,然后运用MATLAB软件对接入信道部分进行设计,并逐步地对各个模块进行分析、仿真与验证。目的是通过毕业设计工作熟悉现代无线通信系统的基本构成与基本工作原理-CDMA (communication system to select the access channel simulation and analysis of parts. First of all, by learning the theory of knowledge, familiar with the access channel to achieve the process, with each step deeper understanding of the principle, at the same time, but also familiar with the software MATALB and understanding of the MATLAB software and its internal part of the SIMULINK use of the CDMA module and parameter settings are familiar with, and then use MATLAB software to access parts of the design of channel and step by step analysis of each module, simulation and verification. The purpose of design work through graduate familiar with the modern wireless communication systems constitute the basic and fundamental principle,)

fft
本文提出了一种采用六项余弦偶次幂窗三峰插值的算法来对电网谐波进行检测与分析。该算法通过分析电网信号加窗后傅里叶变换的频域表达式,利用谐波频点附近的三根离散频谱的幅值确定谐波谱线的准确位置,进而得到电网谐波的相关参数频率、幅值及相位的计算公式,最后再对其进行加权修正,从而进一步的提高检测的准确度和有效性。( this paper proposes an approach for power network harmonic detection and analysis based on six even order cosine window and triple-spectrum-line interpolation. Through analyzing the adding window signal fourier transform in the frequency domain expression, using amplitude of three discrete spectrum near the harmonic frequency point to determine the accurate position of the harmonic spectrum and get the calculation formula of related parameters of the power network harmonic such as frequency, amplitude and phase, the algorithm further enhances the accuracy and effectiveness by using weighted correction.)
