The software is capable to simulate space time code [1] for QPSK modulation using different number of state. Examples of generator matrix up to 256 stetes are provided. Variable signal to noise ratio (SNR) might be applied to produce bit error rate (BER) or frame error rate (FER) curves.(The software is capable to simulate space time code [1] for QPSK modulation using different number of state.

两种噪声下，卡尔曼滤波的100次Monte Carlo仿真验证，画出了每时刻卡尔曼预测均方根误差和估计均方根误差的Monte Carlo变化曲线(with uniform and Gaussian noise respectively,through 100 Monte Carlo simulations,output thecurves of sampled state prediction variances and estimate variances of kalman filter in each element vs.time step.)

好用的程序,多去查资料，你会有很大的收获(good)

生成拍波信号：由自己控制采样频率，拍波频率，拍波个数，拍波周期数和拍波之间的时间间隔和拍波幅值，能生成符合上述要求的任意拍波。(Generate beat-wave signal: control by its own sampling frequency, beat-wave frequency, the number of beat-wave, beat-wave cycles and the time interval between the beat-wave amplitude and beat, meet the above requirements can generate any beat-wave.)
