用DFT (FFT)对连续信号进行频谱分析(Spectrum Analysis of Continuous Signals Using DFT (FFT))

说明：  生成2KHz和8KHz的混合信号,使该信号通过上述滤波器,观察滤波前后的波形变化和频谱分布情况, 在改信号中加入高斯白噪声,(The mixed signal of 2KHz and 8KHz is generated so that the signal passes the above filter, the waveform change and spectrum distribution before and after filtering are observed, and Gao Si white noise is added to the modified signal.)

说明：  VB6.0开发道闸控制程序，程序控制开闸、落闸(failed to translate)

Security in Mobile Ad Hoc Networks

该程序为bellhop多径信道模型，其通信距离为5KM(The procedure for the bellhop multipath channel model, the communication distance of 5KM)

这是研究欧洲DVB-T标准的一套合集，主要介绍了DVB-T单频网的同步技术，以及系统设计和实现。其中对DVB-T单频网进行了详细的讲解，对研究我国的数字电视广播技术也有很好的借鉴作用。(This is the study of the European DVB-T standard a collection, mainly introduces the synchronization technology of DVB-T single frequency network, and the system design and implementation. It make a detailed explanation of DVB-T single frequency network, also have a very good reference for digital television broadcast technology research in china.)

说明：  对语音编码技术的特点进行了分析与研究, 对波形编码,声码器和混合编码三种主要 的语音编码进行了比较, 并介绍了GSM 和CD(This paper analyzes and studies the characteristics of speech coding technology, compares the three main speech codes: waveform coding, vocoder and hybrid coding, and introduces GSM and CD.)

利用改进型APSO算法可以明显抑制噪声 ，可以直接运行(The improved APSO algorithm can obviously suppress the noise and run directly.)
