PN4
- 语言：VHDL 功能：该PN4序列的特点为将一个4位序列的前两位取异或，再让序列左移一位，用异或的结果作为序列的最后一位。序列周期是15，即15位伪随机序列。其中包括序列的产生模块和检测模块。对于误码检测，首先捕获相位。然后，规定测试的码的总个数，统计这些码中有多少个不能满足PN序列特点的，用计数器统计个数。如果发现误码过多，可能是相位失调，重新捕获相位，再进行误码检测。 仿真工具：modelsim 综合工具：quartus -Language: VHDL function:

trans_sigPnoisePinterference
- 根据直扩原理，首先有随机数发生器产生一系列二进制信息数据（+1，-1），每个信息比特重复Lc次，Lc对应每个信息比特所包含的伪码片数，包含每一比特Lc次重复的序列与另一个随机数发生器产生的PN序列c(n)相乘。然后在该序列上叠加高斯白噪声和形式为i(n)=Acosw0n余弦干扰下次信号，切余弦干扰信号的振幅满足条件A<Lc。在解调器中进行与PN序列的互相关运算，并且将组成各信息比特的Lc个样本进行求和。加法器的输出送到判决器，将信号与门限值0进行比较，确定传送的数据为+1还是-1，计数器用
