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)

Matlab程序，实现了一种新的色彩白平衡算法。 针对物体在有色光源照射下呈现偏色的现象,提出一种改进的LoG边缘自动白平衡算法。该算法在YCbCr空间的Cb和Cr分量上同时利用LoG算子提取边缘,利用LoG边缘具有零交叉特性直接得到边缘两侧的像素。为了避免占主导的彩色纹理造成干扰,利用白色区域的偏色信息进行边缘抑制。利用得到彩色边缘对原图的偏色进行有效的估计,最后计算三颜色通道的增益并进行白平衡。对大量图片进行了实验,结果表明该算法对不同色光照射下的图像均能很好地进行白平衡,同时与多种白平衡算法的对比实验表明该算法适应面广,性能良好。
