OFDM程序示例：采用64子信道，应用16QAM传输，每个子载波均传输相同的比特数4，不使用信道编码；使用迫零均衡和MMSE均衡，比较两者性能。(OFDM procedures Example: a 64-channel, application 16QAM transmission, each transmission subcarriers are the same number of bits 4, do not use channel coding the use of force balance and MMSE zero balance, compare the performance.)

DSP matlab应用这本书中的里例程，主要是第5掌的(DSP matlab application of this routine in this book is mainly in charge of section 5 of the)

车牌检测与识别技术的相关技术： 提出一种梯度增强法对图像边缘进行增强, 该方法主要通过对图像本身信息进行简单梯度变换以突出图像边缘, 并辅以数学形态学中的膨胀法实现牌照的快速定位. 在字符分割部分, 给出了最小面积旋转法以确定牌照的最佳旋转角, 并采用垂直投影法分割牌照中的字符 (License plate detection and recognition technology related technologies: a gradient-enhanced method of image edge enhancement, the method of the image itself, mainly through a simple gradient transform information in order to highlight the image edge, supplemented by mathematical morphology in the expansion of law implementation License Express location. in the character segmentation part, give a minimum area of rotation method to determine the best rotation angle license and using the vertical projection of the character segmentation license)
