ABSTRACT:
Interleaving improves noise rejection in digital communication and storage systems. According a known scheme, the interleaving/deinterleaving is achieved by storing symbols in a temporary memory table of R rows×C columns in a row by row order, and reading them in a column by column order, or vice versa, so obtaining a rearranged order. Methods and devices for interleaving and deinterleaving are proposed which accomplish the same interleaving/deinterleaving operation with a reduced size of the temporary memory table. The rearrangement of the symbols according to the rearranged order is accomplished by using a table with a reduced memory size, in combination with the order with which the symbols are fetched from or stored in a further memory. The invention further relates to ICs and apparatuses for interleaving and/or deinterleaving.
