signal preprocessing

在进行车牌识别的预处理过程中,如何有效地提高车牌图像质量是一个关键,这一步处理的好坏将直接影响到后面车牌识别的效果。 本文重点研究直方图修改技术增强图像方法在车牌识别预处理中的应用,给出了直方图修改技术的原理,以及直方图均衡化、规定化和对比度调整的原理,最后用MATLAB来实现车牌图像增强的效果。(License Plate Recognition in the pre-treatment process, how to effectively improve the image quality license plate is a key to dealing with the merits or demerits of this step will directly affect the effectiveness of the back license plate recognition. This article focuses on the image histogram modification method to enhance license plate recognition in the pre-processing of applications, given the principle of histogram modification techniques, as well as histogram equalization, contrast adjustment provisions and the principles of using MATLAB to achieve the final vehicle the effect of brand image enhancement.)

说明：  讲述基于QPSK调制在高斯，瑞利，CorrRayleigh信道下的误码分析。(About QPSK modulation in the Gaussian, Rayleigh, the CorrRayleigh channel bit error analysis.)

阵列分析与综合入门代码，含比较好的绘图模块(Array analysis with the entry code, with better graphics module)

A 2by3 MIMO model using Simulink. The decoder uses zero forcing algorithm. Set in the workspace the modulation order (QAM modulation), Doppler shift, SNR in dB, bit rate, sample per frame, max number of bits and max number of errors before running the simulation. Works also with BERTool but change the BER variable to ErrorVec. Included in the file a BER session with multiple runs and a figure for several runs.
