做信号处理的时候经常会用到FFT，而MATLAB自带的FFT只能变换出一列系数，想做成频谱图还要自己加一部分，自己写了一个小程序，输入原始信号和采样率，可以画出标准的幅值谱和功率谱。(Do signal processing is often used when the FFT, and FFT MATLAB own transformation from a coefficient of only wanted to make Canada part of the spectrum but also their own, to write a small program, the input original signal and the sampling rate can be Draw a standard amplitude spectrum and power spectrum.)

本论文中，一个混合载波频率偏移估计方案用于基于通用滤波多载波的系统。 此方案所述CFO估计器基于最小平方（LS）准则首先导出以获得粗略频率偏移估计使用大频率搜索步骤。 接着，通过其精确估计残留频率偏移自相关操作补偿。 该算法具有较大估计的特点范围以及更高的估计精度。(In this letter, a robust hybrid carrier frequency offset (CFO) estimation scheme based on training symbols is devised for universal-filtered multi-carrier (UFMC) based systems. In this scheme, the CFO estimator based on a least square (LS) criterion is firstly derived to acquire a coarse frequency offset estimation with the use of a large frequency searching step. And then, the residual frequency offset is accurately estimated through the auto-correlation operation of received signals which have been compensated. This algorithm has the features of larger estimation range as well as higher estimation precision.)

正交频分复用(OFDM)技术是一种可以有效对抗符号间干扰(ISI)的高速数据传输技术。OFDM是一种特殊的多载波调制方式，它的基本思想是将高速传输的数据流通过串/并转换，变成在若干个正交的窄带子信道上并行传输的低速数据流。OFDM接收机有三个关键技术：信道估计技术，降低峰均比(PAPR)技术和同步技术。OFDM技术能有效的对抗多径衰落等，有着诸多的优点，但是OFDM有一个发展瓶颈，即OFDM信号的峰均功率比很大，很容易导致OFDM信号的交调失真和系统性能的下降。因而如何降低OFDM信号的峰均功率比一直是OFDM技术的一个研究热点问题。论文针对上述问题，重点研究了降低OFDM信号的峰均功率比的SLM与PTS算法，并利用Matlab对算法进行了仿真研究，并对仿真结果进行了分析。(Orthogonal frequency division multiplexing (OFDM) is a high-speed data transmission technology that can effectively combat inter-symbol interference (ISI). OFDM is a special multi-carrier modulation method, its basic idea is to high-speed transmission of data stream through the serial/parallel conversion, in a number of orthogonal narrowband sub-channel parallel transmission of low-speed data stream. OFDM receivers have three key technologies: channel estimation techniques, reduced peak-to-average ratio (PAPR) techniques and synchronization techniques. OFDM technology can effectively combat multipath fading, etc., there are many advantages, but OFDM has a bottleneck in development, that is, OFDM signal peak power ratio is large, it is easy to lead to OFDM signal intermodulation distortion and system performance degradation. Therefore, how to reduce the peak-to-average power ratio of OFDM signal has been a hot topic in OFDM technology. In this paper, the SLM and PTS algorithms for reduc)
