OF,实际上OF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。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。在向B3G/4G演进的过程中，OFDM是关键的技术之一，可以结合分集，时空编码，干扰和信道间干扰抑制以及智能天线技术，最大限度的提高了系统性能。(OF)

Color Image Enhancement Techniques:
A Critical Review
Abstract
Image enhancement is one of the key issues in high quality pictures such as digital camera and HDTV. Since
Image clarity is very easily affected by lighting, weather, or equipment that has been used to capture the image.
These conditions lead to image may suffer from loss of information. As a result, many techniques have
developed known as image Enhancement techniques to recover the information in an image. This paper presents
a literature review on some of the image Enhancement techniques for color image enhancement like, Contrast
Stretching, Histogram Equalization and its improvement versions, Homomorphic Filtering, Retinex, and
Wavelet Multiscale Transform. Comparison of all the techniques concludes the better approach for its future
