there are some newly released Neural Network Example Programs for Character Recognition, which based on Image Processing Toolbox,Neural Network Toolbox in MATLAB, which is quite informative for the beginners in Neural networks applicators(there are some newly released Neural Network Example Programs for Character Recognition, which based on Image Processing Toolbox, Neural Network Toolbox in MATLAB, which is quite informative for the beginners in Neural networks applicators)

Generation of ASK: Amplitude shift keying - ASK - in the context of digital communication is a modulation process which imparts to a sinusoid two or more discrete amplitude levels 1. These are related to the number of levels adopted by the digital message. For a binary message sequence, there are two levels one of which is typically zero. Thus the modulated waveform consists of bursts of a sinusoid. Demodulation of ASK: ASK signal has a well defined envelope. Thus it is amenable to demodulation by an envelope detector. Some sort of decision-making circuitry is necessary for detecting the message. The signal, which is a binary sequence is recovered by using a correlator and decision making circuitry.

设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK a variety of modulation and corresponding demodulation mode, the main (sub-coherent and non-coherent) and bit error rate statistics, and compared with the theoretical value , a graphical representation of the bit error rate and SNR relationships.)

为matlab添加启动画面的另一种方法，也是从matlab论坛上得到的(Add a splash screen for the matlab another way, is also obtained from the matlab forum)
