spectrum sensing for cognitive radio using energy detection

在matlab中构成不同频率的调制信号，这些函数都是以fm开头，产生常数、双曲线、线性、抛物线等频率调制信号．(in Matlab, constitute a different frequency modulation signal, these functions are beginning to fm, have a constant, hyperbolic, linear, parabolic and other frequency-modulated signal.)

可以产生不同调制方式的信号，包括bpsk,qpsk,fsk,msk,16qam,64qam.可以产生不同的样本。(Can generate a signal of different modulation methods, including bpsk, qpsk, fsk, msk, 16qam, 64qam. Can produce different samples.)

针对样本协方差矩阵求逆方法中采样点小于阵元个数时作出的仿真。此改进方法可以在采样点小于阵元个数时提高波束形成器的性能。(For the sample covariance matrix inversion method of sampling is less than the number of array elements made the simulation. This improved method can be sampled at less than the number of array elements to raise the beamformer performance.)

Keogh的SAX聚集近似算法，首先采用PAA分段，然后正态化序列，在对应表上查询符号表示，这是一个很经典的时间序列表示方法(Keogh' s SAX gathered approximation algorithm, the first use PAA segment, then normal sequence, query on the corresponding symbol table indicates, this is a classic representation of the time series)

matlab中的wave文件添加功能，欢迎使用(Matlab the paper added wave function, welcomed the use of)

1. to calculate FFT real-time 2. to control the brightness of your picture real time 3. to make frames from your audio files

说明：  通信系统关键技术仿真--比特加载算法 函数完成在给定子信道信息、误码率和码元速率的前提下子信道的比特分配。(Key technology communication system simulation- bit loading algorithm function to complete in a given sub-channel information, the error rate and symbol rate sub-channel under the premise of the bit allocation.)

工程热力学利用P-R方程求解纯质制冷剂的PVT性质。制冷剂可以为R22，R600a等(Engineering thermodynamics using P- R equation pure mass PVT properties of refrigerants.For refrigerant R22, that R600a, etc)
