BFSK demodulator written for matlab

简单的信道化处理信号，输入不同的信号中心频率点会得到不同信号的输出从而分离出输入信号，代码较简单直观(Simple channel processing signal, the input signal different center frequency will be output different signals to separate the input signal, the code is relatively simple and intuitive)

将实信号变换为复信号，提取信号幅值、相位角，计算相位同步指数，分析各组信号数据之间的同步稳定性。(The signal is converted into a complex signal, extraction of signal amplitude, phase angle, calculation of phase synchronization index, analysis of stability of synchronization between each signal data.)

有限差分波场模拟利用声波方程进行有限差分正演模拟。(the simulation of acoustic wave.using the acoustic wave equation. in the program i deal with the edge and the result.)

OFDM信道估计的几种方法的仿真，包括最小二乘(LS)法、最小均方误差(MMSE)法、线性最小均方误差(LMMSE)法以及奇异值（SVD）分解法等，毕设资料，非常珍贵(several OFDM channel estimation methods,which contains the least-squares (LS), the minimum mean square error (MMSE), the linear minimum mean square error (LMMSE) and the singular value decomposition (SVD))

mc-ds-cdma系统仿真，Matlab版(mc-ds-cdma system simulation, Matlab version)

主要实现一无人自行车的控制自主导航，可对导航与控制进行说明(The main achievement of a bicycle control unmanned autonomous navigation, navigation and control can explain)

high boost filter for frequency domain

说明：  多目标优化的例证，用粒子群算法做的。调试过，没问题，能用。(multi-objective ,PSO)
