该函数为求解信号的过零率的matlab函数(matlab function used for the zero—pass of signal)

After identifying the best MNT− 1 nodes with the simplified branch metric and the accumulated branch metric at stage NT − 1, we then calculate the LLR of each coded bit utilizing the standard squared Euclidian distance metric. The log-likelihood ratio (LLR) of a posteriori probability (APP) of each coded bit conditioned on the received signal y is normally calculated using the max-log approximation.

产生固定周期数的正弦脉冲信号 使用该函数时必须预先设定如下参数：正弦波的频率Fp，构成输出脉冲的正弦波的周期个数Nc，脉冲幅度A每个周期的采样点数smp。函数有两个输出：脉冲波形，以响亮sinpulse的形式输出，采样周期dt。(Produce a fixed number of cycles of the sine pulse signal         Use this function must be pre-set the following parameters: a sine wave of frequency Fp, constituting the output of the pulse cycle of the sine wave of the number Nc, the sampling points for each cycle of the pulse amplitude A smp. The function has two outputs: output pulse waveform, the a loud sinpulse form, the sampling period dt.)

在过零检测过程中，找过零点，并以此来进一步计算相位差等(In the zero-crossing detection to find the zero crossing, and to calculate the phase difference)

Floyd的Matlab教程，很简单。。 几行代码而已。(Floyd' s Matlab tutorial, very simple. . A few lines of code.)

卡尔曼静态滤波在GPS量测数据中的应用。静态模型以待测点的位置和速度作为状态变量，假定系统噪声和量测噪声为高斯白噪声。多数情况下将其看成是一个线性系统。( Application of Calman static filtering in GPS measurement data. The static model is used as the state variable, and the system noise and measurement noise are Gauss white noise. In most cases, it is considered as a linear system. )
