可以实现ofdm的LS信道估计，并与未采用估计时进行比较(The LS can ofdm channel estimation, and with no comparison with estimates)

现代通信系统——使用matlab 源程序(Modern communications systems- the use of matlab source)

语音的端点检测是根据语音的特征来进行了，本文根据语音不同帧之间能量的不同，一帧一帧的进行比较(Speech endpoint detection is based on the characteristics of voice, different voice between the different frames of energy, a one to compare)

根据第一层材料禁带宽度与第二层材料禁带宽度，绘制不同损失率下，两种材料禁带宽度随损失率变化的关系曲线以及双层材料光伏转换极限效率曲线(According to the first layer of material with a band gap of the material the band gap of the second layer, draw a different loss rate curves of the two materials with the band gap of the rate of change and the loss of bilayer material photovoltaic conversion efficiency curve limit)

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules(This packet is a IS-95 baseband simulation for a channel data rate of 9.6 KBps.

提出改进型的节点重构小波包频带能量谱与 PNN（概率神经网络）的联合故障诊断新方法。 有具体的数据和程序，经过本人验证的，程序有效！效果很好！(Joint fault diagnosis node propose a new method for the reconstruction of improved wavelet packet energy spectrum band and PNN (probabilistic neural network). Specific data and programs, after I verified, the program works! Works well!)

说明：  故障诊断程序 支持向量机智能诊断 分为多个程序 数据输入、特征提取、功能函数等(Fault diagnosis procedure Intelligent diagnosis of support vector machine It is divided into several program data input, feature extraction, function function, etc)

8psk modulation is done using simulink model in this document. hope u get knowledge
