offset quadrature amplitude modulation

说明：  基于matlab用神经网络的一组数预测，数学建模里比灰度预测好用(Een reeks nummervoorspelling op basis van matlab met behulp van een neuraal netwerk, wat beter is dan grijze voorspelling in wiskundige modellen)

产生2fsk或4fsk的调制信号，可以控制带宽，中心频率，噪声，可以观察频谱(this can product signal)

利用matlab处理，计算所有点数，计算每个色阶的次数，限定0-1范围内，再累加再影射输出(Processing using matlab to calculate all the points, calculate each color scale the number of times, limited the range of 0-1 accumulate again alluding output)

说明：  我不太会用matlab，这就是一个用过来实现DPC的算法(Implementation of DPC)

通过时空变换的方法对超声导波模态提取，可以用于声发射和超声导波提取模态用(Through time and space to transform Ultrasonic Guided Wave Mode extraction, can be used for acoustic emission and ultrasound guided modal wavelet extraction using)

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)
