DTMF (触摸口气) 信号音生成和检测

Decompose image into subbands (undecimated wavelet), denoise, and recompose again. fh = decomp_reconst_wavelet(im,Nsc,daub_order,block,noise,parent,covariance,optim,sig) im : image Nsc: Number of scales daub_order: Order of the daubechie fucntion used (must be even). block: size of neighborhood within each undecimated subband. noise: image having the same autocorrelation as the noise (e.g., a delta, for white noise) parent: are we including the coefficient at the central location at the next coarser scale? covariance: are we considering covariance or just variance? optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0) sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise) Javier Portilla, Univ. de Granada, 3/03 Revised: 11/04

char和CString之间赋值的问题，包含char* 转化成 CString，CString 转化成 char* ，BSTR 型转化成 CString 型等等。(between the char and CString assignment problem with char* into a CString, CString into a char*, BSTR type into CString type and so on.)

说明：  共同学习，共同提高，资源共享 一个产生bpsk信号的例子，可以推出MPSK的调制基带信号(studying together, enhancing and sharing resources have BPSK signals an example, can be introduced MPSK the baseband signal modulation)
