摘　　要：本文设计了一种基于DVB-C的卷积解交织器,利用两个静态随机存取存储器(SRAM)来实现.用一SRAM来存储解交织的数据,读写共用一个地址,由基地址和偏移地址组成.同时,用另一SRAM来存储偏移地址.结果表明,卷积解交织器能实现功能,而且减小了电路复杂度,缩小了面积.This paper presents a convolutional deinterleaver implemented with two SRAM,which is based on DVB-C.A SRAM is used for storing input data.There is one address for read and write which comprise two parts,a start address and the offset address.Another SRAM is used for storing the offset address.The results show that the convolutional deinterleaver achieves the expected function.The complexity and the area has been reduced.
