Function matlab to plot points with more flexibility

数字信号处理的基本内容，并且加上matlab的实现(The basic elements of digital signal processing, and implementation with matlab)

ecent advances in electrical engineering and computer science, esp ecially in micro- electro-mechanical systems (MEMS), very-large-scale integration (VLSI) and op erating system theory, have made wireless sensor network (WSN) technologies an imp ortant and promising research area. As the circuitry b ecame smaller and cheap er, the idea of co op eratively sensing physical or environmental conditions, such as magnetic eld intensity, temp erature, light intensity, sound, vibration, pressure, motion or p ollutants with the help of a network of sensor no des has b ecome feasible.

ISAR问题，使用块之间的耦合关系的ISAR问题，这样做不用考虑对块进行分割，避免使用块分割的先验信息(Using a block of the coupling relationship between ISAR problem, not considering the block segmentation, avoid using block segmentation of a priori information)

针对无线射频识别(radio frequency identification，RFID)系统的多标签碰撞问题，在分析RFID标签编码规则的基础上，提出根据标签编码规则进行标签分组和标签预淘汰的方法，在读写器识别的初始阶段根据特定的规则淘汰部分标签，从而减少系统工量，提高系统工作效率.实例证明：在不增加标签结构复杂度的基础上，充分利用已有的有效信息能够有效减少阅读器的查询次数和系统的总通信量．(For radio frequency identification (radio frequency identification, RFID) system is a multi-tag collision problem, based on the analysis of the RFID tag encoding rules based on the proposed label grouping and labeling pre-elimination method according to the label encoding rules identified in the initial reader phase-out of the label according to specific rules, thus reducing the amount of system engineering, to improve system efficiency examples demonstrate: the label without increasing the complexity of the structure on the basis of full and effective use of existing information can be effective in reducing the number of queries and reader total traffic of the system.)
