摘要
本文分析了卷积交织和解交织的基本原理,然后采用Altera的FPGA器件,用RAM分区循环移位法来实现解交织器。无论从理论上,还是从计算机仿真和综合结果上来分析,都可以看出用这种方法来实现DVB-C解交织器能有效地节省硬件资源。
This paper analyses the basic principle of the convolutional interleaver and de-interleaver, then designs the de-interleaver with dual-port RAM by using FPGA. From the analysis in theory and the result of computer simulation and synthesis, we can know that this method has many advantages in saving the hardware resource.
