　OFDM —— OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。此程序为ofdm仿真程序！(OFDM- OFDM (Orthogonal Frequency Division Multiplexing) that is orthogonal frequency division multiplexing, OFDM is the fact MCM Multi-CarrierModulation, a multi-carrier modulation. The main idea is: The channel is divided into a number of orthogonal sub-channel, high-speed data signals into parallel low-speed sub-data stream, modulated to be transmitted in each sub-channel. This program is ofdm simulation program!)

DWT is any wavelet transform for which the waveletsDaubechies wavelets are discretely sampled. The code uses

分数阶统计是现代统计信号处理的重要内容，这里是alpha、beta分布的情况，仿真程序(Fractional statistics is an important content of modern statistical signal processing, where alpha and beta distribution emulator)

将传统跳频系统中不变的的跳速以及跳频间隔加入时变特性，增强系统的抗干扰性能(Join traditional frequency hopping systems in the same jump speed and hopping interval time-varying characteristics, enhanced anti-jamming system performance)

线性调频脉冲压缩的Matlab程序,用于建立主成分分析模型，最终的权值矩阵就是滤波器的系数，包括脚本文件和函数文件形式，与理论分析结果相比，可以动态调节运行环境的参数，可以得到很精确的幅值、频率、相位估计。( LFM pulse compression of the Matlab program, Principal component analysis model for establishing, The final weight matrix is ??the filter coefficient, Including script files and function files in the form, Compared with the results of theoretical analysis, Can dynamically adjust the parameters of the operating environment, You can get a very accurate amplitude, frequency, phase estimation.)
