- 用C51编写的基于51单片机串口点对点双向通信程序,特点是具有可靠的通信失败检测及信息重发功能。-with C51 prepared by the 51 microcontroller-based point-to-point two-way serial communication program, which is characterized with reliable communication failure detection and re-issued the information
simple tank
- 同样是用j2me写的,只是这个tank.rar实现了最基本的冲突检测,也就是j2me中最基本的问题,应为坦克运动时,会碰壁,而这个程序中较好的做到了这一点。而且,其中也实现了积分的操作,数据库读写。-J2ME is the same writing, only the tank.rar realization of the most basic conflict detection, J2ME is the most basic issues, the movement of tanks, it
dtmf
- 本程序用于检测音频文件中是否具有DTMF信号,若有则将其检出。 程序首先使用Goertzel算法求出以FRAMESIZE(默认200)为大小的一帧数据在8个DTMF频点上的能量。 对Goertzel算法的改进,对于系数的计算不是采用2*cos[2*pi*k/N],而是采用2*cos[2*pi*fn/fs],这样能够降低误差。 确定了8个频点的能量后运用一系列判决门限来确定有没有DTMF信号,以及信号是什么。 -This procedure used to detect wh
grd_test
- xwch_test.m是主测试文件;biaoji.mat存放滤波器系数;xiangweicha.m用FFT计算相位差。 仿真框架为: 1.标记信号和双音信号续接作为发送信号; 2.对双音中一个频率分量的相位做偏移,再经过一个低通滤波器(引入线性相位,模拟收发不能同步测量现象)后,作为收到的信号; 3.用一个检测信号对收发信号进行相关运算; 4.画出收发信号以及相关处理后的信号。找出相关信号的那个尖点,从而推算出收发双音信号0相位点; 5. 输入0相位点位置,计算

- 针对宽带高分辨雷达体制下的未知速度运动目标检测问题, 基于高分辨一维距离像提出一种新的非相干积累算法. 首先利用改进的双向维特比算法估计目标速度及强散射点位置, 提高了低信噪比下 的估计精度, 然后在强散射点周围选取待检测单元进行非相干积累, 进一步提升了检测性能. 两类飞机实测数据的多个实验结果表明, 当目标发生距离走动的情况下, 该算法性能相对传统的非相干积累算法有明显的提高.-For unknown broadband speed moving target detection pro
