本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解， 以说明三种取阈值方法和三种噪声标志对去噪性能的影响。(This procedure Mr. Cheng a " Blocks" signal, and then adding white Gaussian noise, and then ' db3' wavelet decomposition, to illustrate the three kinds of check-threshold method and three kinds of noise, signs of de-noising performance.)

多经环境下的锐利衰减信道的估计，仿真，测量以及获得相应的指数等的(using this model you will achieve the performance of the rayleigh fading channel issue)

用DSM调制1-bit输出，经简单模拟滤波电路，产生VGA控制电压。对于内部频率高、但VGA变化速度较慢的场合，可以达到很高的控制精度，从而省却了内部高精度DAC的模块(DSM modulation with 1-bit output, through a simple analog filter circuit, producing VGA control voltage. in the circumstance of high internal frequency, but need a slower changing VGA control, this program can achieve high control precision, and thus save the internal high-accuracy DAC module)

求解一个方程，用画图命令，将求解的过程描述出来(Solving an equation, with the drawing command, describe the process of solving)

说明：  Today’s wireless networks are characterized by a fi xed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15 to 85 with a high variance in time. The limited available spectrum and the ineffi ciency in the spectrum usage neces- sitate a new communication paradigm to exploit the existing wireless spectrum opportunistically
