Digital image and signal processing using matlab

说明：  超高频RFID读写器研究与设计 本课题以超高频RFID读写器硬件实现为主要本文设计RFID读写器硬件基带和射频部分的参数都可以满足要求，读写器可 以正常读、写符合15015000一6C或者 EpCglobalClasslGenZ协议的电子标签， 其上传速率可以达到640kbPs，配合上层的软件设计可以实现读写器考勤功能，经 过测试验证本系统可以长时间地稳定工作。 (UHF RFID reader research and design of this issue using the UHF RFID reader hardware designed in this paper as the main RFID reader hardware, baseband and RF part of the parameters are to meet the requirements of a normal reader can read, 15.015 million was in line with the agreement of a 6C or EpCglobalClasslGenZ electronic tags, its upload speeds can reach 640kbPs, with the top of the software design can be achieved reader attendance functionality, the system can be tested and verified for a long time stable jobs.)

闭环buck电路实例，具有抗扰动功能，参考电压自行设置(Closed-loop buck circuit instance, the anti-disturbance feature, the reference voltage to set)

麦克风语音增强算法的研究，原理是经麦克风采集的语音信号，经过功放使所需的信号增强(Microphone speech enhancement algorithm, the principle is captured by the microphone voice signal, the signal through the amplifier to make the necessary enhancements)

DES function for the encryption of DES,use matlab to make it possible,first input in the function is plaintext ,second one is key,and last is to choose encrypt or decrypt

用MATLAB实现信道化，可以根据自己的需求改变信道数，有仿真图(Using MATLAB channelization, you can change the number of channels according to their needs, there are simulation map)

In this simulation, a 2 x 2 MIMO system with BPSK modulation is used. Then, the algorithm of V(BLAST is implemented. After that, weight vector is produced using ZF, MMSE and ML detectors. Finally, the BER performance is plotted. A flat fading Rayleigh channel is assumed in this simulation.)

说明：  由 得到幅频响应 。系统函数 由下式给出： （A.1） 若 ，则 为一全极点IIR系统，若 ，则 为FIR系统(By the frequency response obtained. System function is given by: (A.1) if, compared to an all-pole IIR system, if, for the FIR system)

实现带有再采样步骤的rjmcmc算法，并用算例证明其性能。(To achieve with the re-sampling step rjmcmc algorithm, and use examples to prove its performance.)

this code helps to solve genetic algorithms
