Abstract
Methods and corresponding systems in an interleaver include loading K symbol data, in a linear order, into a matrix memory having (R·C) storage locations corresponding R rows and C columns. A sequence of interleaved addresses is produced for reading the K symbol data in an interleaved order from the matrix memory. Next, (R·C)−K interleaved addresses are queued in a first-in-first-out (FIFO) memory. After queuing (R·C)−K interleaved addresses in the FIFO memory, symbol data is output using the interleaved addresses in the FIFO memory to address and output the symbol data in the matrix memory in the interleaved order. The FIFO memory can contain at least 234 memory locations.
