GPS
利用Matlab生成GPS C/A 码的基带信号。
(1)产生卫星PRN 号码为“5”的一组C/A 码;
(2)循环生成25 页的导航数据,GPS 时间可填入一固定的已知数值;
(3)生成C/A 码扩频信号,每个C/A 码码片给出4 个采样数据;
(4)基带信号采用方波信号,电平为0 和1,占空比为50 %,不加入噪声,进一步生成某个特定的中频信号。(Matlab generated using GPS C/A code base band signal. (1) generation of satellite PRN number is " 5" a set of C/A code (2) loop generates 25 of the navigation data, GPS time can fill a fixed known value (3) to generate C/A code spread spectrum signal, each C/A code chip gives the four sampling data (4) baseband signals using square wave signal, level 0 and 1, 50 duty cycle, not to join the noise generated further a specific frequency signal.)

律u律pcm编码
若输入A律PCM编码器的正弦信号为x(t)=sin(1600πt),采样序列为x(n)=sin(0.2πn),n=0,1,2,…,10,将其进行PCM编码,求出编码器的输出码组序列y(n)。
要求:1) 直接采用A律扩展器函数求解上述问题。
2)使用13折线法近似A律PCM 求解上述问题。
3)计算量化误差。(Law a law pcm coding
If the input A-law PCM encoder is sinusoidal signal x (t) = sin (1600πt), for the sample sequence x (n) = sin (0.2πn), n = 0,1,2, ..., 10, it will be PCM coding to obtain the coded output code group sequence y (n).
Requirements: 1) directly A-law expander function to solve the above problems.
2) using a 13 fold line approximation A-law PCM to solve the above problems.
3) calculating the quantization error.)
