QPSK BPSK qam的AWGN和瑞利信道的生成和仿真(QPSK BPSK qam of AWGN and Rayleigh Road, generation and simulation)

VCPSO, Particle swarm optimization with velocity clamping

首先一个是基于JAKE模型的多径衰落信道模型及性能分析。另外一个是OFDM系统中基于上述信道模型的性能分析。(JAKE first model is based on a multipath fading channel model and performance analysis. Another system is the OFDM channel model based on the above analysis of the performance.)

In this paper, the concepts of Daubechies wavelet transform are discussed. The Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support. With each wavelet type of this class, there is a scaling function which generates an orthogonal multi resolution analysis.

MATLAB命令大全，学习资料，非常全面。(MATLAB command Daquan, learning materials, very comprehensive.)

时频分析工具箱中提供了计算各种线性时频表示和双线性时频分布的函数(Time-frequency analysis toolkit provides the calculation of linear time-frequency representation and bilinear time-frequency distribution function)

MATLAB建模与仿真应用资源，内含丰富源码(MATLAB modeling and simulation application resources)

用MATLAB对OFDM系统进行了仿真分析。包括信道调制方式16QAM、快速傅立叶变换、循环前后缀及信道函数窗函数等，最后计算了系统的误码率，毕设资料，非常珍贵。( MATLAB OFDM system for the simulation. the simulation uses OFDM each function module, Including 16 channel modulation QAM, Fast Fourier Transform, revolving around prefix and channel Function window function, etc. Finally, Calculate BER for OFDM system)

测距仪测距的过程中，由于受到仪器本身的系统误差以及外界环境影响，会造成测距精度的下降。为了提高测距的精度，我们需要对测距的结果进行改正，可以分为三种类型的改正：仪器常数的改正、气象改正和倾斜改正。(Rangefinder ranging process, due to systematic errors in the instrument itself and the external influences, ranging accuracy will result in a decline. In order to improve ranging accuracy, we need to correct the results of the distance, can be divided into three types of corrections: the correction instrument constant, meteorological correction and inclination correction.)
