This is a simple Simulink model for digital PAM in AWGN channels.

GPON 标准 GPON ITU 标准 G984.1-2003 (GPON ITU standard G984.1-2003)

说明：  BPSK的调制解调以及误码率等的matlab仿真(BPSK modulation and demodulation, and bit error rate of matlab simulation)

数字控制器频点调整，包括频点上移动或者向下移动的程序(digital nco)

说明：  （拟合） 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。 如果作2或4次多项式拟合，结果如何？ ((Fitting) with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add a random disturbance yi ( can be generated rand (0,1) uniformly distributed random number, or rands generated N (0,1) distribution of random numbers), and then added with xi and yi for random interference of the 3 times polynomial fitting, and the original coefficient. If 2 or 4 times for polynomial fitting, the result?)

Very simple function to quickly plot a 3D cube

This is matlab simulation of selective mapping technique for papr reduction.Sequences that are independent and represent the same information are generated.PAPR of these are calculated separately. Sequence with the smallest PAPR is selected for final serial transmission
