1/3,k=9的卷积码VHDL实现,在xilinx ise上仿真成功。-1/3, k = 9 convolutional code VHDL implementation of the simulation in the xilinx ise success.

urbo码是1993年法国人Berrou提出的一种新型编码方法。它巧妙的将卷积码和随机交织器结合在一起；同时，采用软输出迭代译码来逼近最大似然译码-urbo code is 1993 French Berrou proposed a new encoding method. It is clever to convolutional codes and random interleaver together the same time, the use of soft-output itera
