Find the bhattachharya coefficient

该程序包实现了VBLAST结构的传输下，接收端采用ZF、ZF_SIC、MMSE、MMSE-SIC等检测算法时误码率和信噪比的性能比较(The package implements the transmission of VBLAST structure, the receiver with ZF, ZF_SIC, MMSE, MMSE-SIC detection algorithm for error rate and SNR performance comparison)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

小波分析理论与MATLAB7实现，是本电子书，需要安装超星电子图书阅读器来阅读。(Wavelet analysis theory and MATLAB7 realization is the e-books, need to install Superstar electronic book reader to read.)

调制识别的传统算法， 零中心归一化瞬时幅度的谱密度的最大值 零中心归一化瞬时幅度绝对值得标准偏差 零中心非弱信号段瞬时相位非线性分量绝对值的标准偏差 零中心非弱信号段瞬时相位非线性分量的标准偏差 零中心归一化非弱信号段瞬时频率绝对值得标准偏差(Traditional modulation recognition algorithm, the zero center owned by an instantaneous amplitude of the spectral density of the maximum zero center owned by one of the instantaneous amplitude is definitely worth the nonlinear component of the instantaneous phase of the absolute value of standard deviation of zero-center non-weak signal segment, standard deviation of zero center weak signal segment of the standard deviation of the nonlinear component of the instantaneous phase zero center owned by the instantaneous frequency of a non-weak signal segment is definitely worth the standard deviation)
