Abstract
Interleavers are used in data transmission and storage applications to introduce diversity into a data stream, thereby making adjacent symbols more independent with respect to a transfer environment of variable quality. Conventional interleavers require storage in whole units of data blocks. This storage requirement complicates implementations for applications where available circuit area is limited and data rates and block sizes are large. A novel interleaver produces an interleaved data block using storage space that is only a fraction of the size of the input data block.
