This paper presents a small-area ISDB-T time deinterleaver structure. ISDB-T is an mobile TV standard that is widely used in Japan and many South American countries. One of the strong points of the standard is the long interleaving depth, which enhance the communication performance. However, long interleaving requires many delay buffers, in other words many pointer registers. This paper reduces the number of pointer registers with the deinterleaver equivalent transformation. The experimental results show that the area is reduced with the proposed structure.
