bpsk的调制与解调的过程，并采用卷积码，讨论其误码性能随着其功率、频偏、相偏而变化.(bpsk modulation and demodulation process and using convolutional codes, to discuss its error performance with its power, frequency offset, phase offset changes.)

复杂噪声背景下，微弱振动信号去噪方法之小波包软阀值去噪(Complex noise background, the weak vibration signal denoising method of wavelet package soft threshold denoising)

说明：  Matlab中对建立好的网络进行节点/连边随机、蓄意攻击，用最大连通子图、网络效率来衡量网络的抗毁性，并找出最关键的节点的仿真程序。(In MATLAB, the nodes / edges of the established network are attacked randomly and intentionally. The invulnerability of the network is measured by the maximum connectivity sub graph and network efficiency, and the simulation program of the most critical node is found.)
