many matlab code with Fftseq ,uniform to gauss AM DSB FM modulation

in this code very useful for designing real number concept

：采用FPGA来实现一个基于OFDM技术的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制器包括：信道编码（Reed-Solomon编码），交织，星座映射，FFT和插入循环前缀等模块。我另外制作了相应的解调器，可以实现上述功能的逆变换。(: Using FPGA to implement a technology-based OFDM communication systems in base-band data processing part of the modem. One part of the modulator launch include: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and cyclic prefix insertion modules. I also produced a corresponding demodulator can achieve the above-mentioned inverse transform function.)

说明：  16位右移位寄存器 下面描述的是一个位宽为16位的右移位寄存器，实际具有环形移位的功能，是在右移位寄存器的基础上将最低位的输出端接到最高位的输入端构成的。其功能为当时钟上升沿到达时，输入信号的最低位移位到最高位，其余各位依次向右移动一位。(16-bit right shift register The following description is a right shift register with a bit width of 16 bits. It actually has the function of circular shift. It is based on the right shift register, which connects the lowest bit output terminal to the highest bit input terminal. Its function is that when the rising edge of the clock arrives, the lowest displacement of the input signal reaches the highest position, and the rest of you move one bit to the right in turn.)
