手机游戏物理模型之抛物线
- 物体做抛物线运动是游戏中基本运动物理模型之一! 在PC游戏中可以由重力公式 轻易模拟,但在手机游戏中 ,由于多数手机不支持浮点运算 因此不能用 sin ,cos, 来分解初速度。 所以只能用近似模拟的方法! 我所采用的是:先放大后缩小的模拟方式,并且为了更精确加入了一定的偏移量。-objects do parabolic movement is the basic game campaign physical model one! The PC game can be easily simula
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

QAM
- QAM是一种矢量调制,将输入比特先映射(一般采用格雷码)到一个复平面(星座)上,形成复数调制符号,然后将符号的I、Q分量(对应复平面的实部和虚部,也就是水平和垂直方向)采用幅度调制,分别对应调制在相互正交(时域正交)的两个载波(cos wt和sin wt)上-QAM is a modulation vector, the first mapping the input bits (Gray code commonly used) to a complex plane (constellation
