说明：  采用频率调制 为1000Ｈｚ的载波，在解调前把加性白高斯噪声加入到调制信号。当噪声功率和调制信号功率比为０.００１，０.０１，０.０５，０.１和０.３是进行解调并绘出调制信号(The use of frequency modulation for the 1000Hz carrier, in the demodulation before AWGN added to the modulation signal. When the noise power and modulation signal power ratio of 0.3 is 0.001,0.01,0.05,0.1 and demodulation and modulation signals mapped)

基于菲涅尔域的双随机相位编码图像加密方案，利用角谱传播法实现(Based on double random phase encoding Fresnel domain image encryption scheme to achieve the use of angular spectrum propagation method)

一种新的符号定时和载波频率同步算法,该算法将OFDM符号分成几部分。它使用相关性和积累在几个OFDM 符号获得估计函数。当部分的长度小于ISI自由地区,该算法可以识别它。然后估计的最优符号定时和载波频率偏移可以获得。计算机仿真结果表明,该算法不仅可以跟踪时变信道变化但也有较小的MSE比ML估计算法。(A new symbol timing and carrier frequency synchronization algorithm is presented and the algorithm divides the OFDM symbol into several parts. It uses correlation and accumulation in several OFDM symbols to acquire estimation function. When the length of part is smaller than that of ISI free region , the algorithm can distinguish it. Then the estimation of optimal symbol timing and carrier frequency offset can be acquired .The computer simulation results show that the proposed algorithm not only can track time varying channel change but also has smaller MSE than that of ML estimation algorithm.)
