短时傅里叶变换源代码 (STFT SOURCE CODE)

Software Digital Filter

接收部分从信道接收信号。经基带滤波、短码解扩、沃尔什解调、解扰、去交织和维持比译码，输出解调后的信号。各通信模块和发射机的相关模块设计类似。(Receiving part receives signals from the channel. The baseband filtering, short code solution extender, Walsh demodulation, cross talk, go to interweave and solution than decoding, maintain the output signal after demodulation. Various communication module and the related module design similar transmitter. )

it describe about brain image segmentation

a new optimization algorithm ,,,, really helpful

说明：  利用matlab仿真软件，实现8QAM调制。在实现时采用正交调幅的方式,某星座点在I坐标上的投影去调制同相载波的幅度,在Q坐标上的投影去调制正交载波的幅度,然后将2个调幅信号相加就是所需的调相信号。(Use of matlab simulation software to achieve 8QAM modulation. In achieving the adoption of quadrature amplitude modulation means of a constellation in the I coordinates of the projection to the modulation of the amplitude-phase carrier, in the Q coordinates of the projection to the range of carrier orthogonal modulation, and then the sum of two AM signals is the required phase modulation signal.)

三种doa估计方法，和比较性能，都能够实现，有capon，music，esprit(Three DOA estimation methods and their performance comparison)

Kalman滤波程序,在一维的数据上，观看滤波后估计值与预测值之间的差距。(Kalman filtering)

很好的射线追踪程序，可以用来进行正演模拟，很实用(Good ray tracing program, can be used for forward modeling, it is useful)
