惯性导航精解算程序，test_error是执行程序(Solver precision inertial navigation procedures, test_error implementation of procedures)

对获得的声音进行处理。得到相关参数的同时进行滤波。以达到降噪的目的。(To deal with and filter a kind of input sound modify the parameters of this voice.)

双音多频，由高频群和低频群组成，高低频群各包含4个频率。一个高频信号和一个低频信号叠加组成一个组合信号，代表一个数字。DTMF信号有16个编码。利用DTMF信令可选择呼叫相应的对讲机。(Dual tone multi-frequency, high-frequency and low-frequency group composed of groups, high-frequency group contains four frequencies each. A high-frequency signal and a low frequency signal is superimposed to form a combined signal representative of a number. DTMF signal has a 16 code. DTMF signaling to the appropriate use of the intercom call.)

现代信号处理随书光盘 matlab 文件(CD with the book of modern signal processing， matlab file)

说明：  快速脊波逆变换。也称为伴随和伪逆。也成为快速三角波逆变换。(Fast Inverse Curvelet Transform.This is in fact the adjoint, also the pseudo-inverse)
