Patent ID: 7408999

Claim:
A communications system having a dynamic interleaver adaptation scheme, the system comprising: an interleaver with an interleaver output speed and an interleaver line rate adapted to receive data and to interleave the received data to thereby generate interleaved data; a de-interleaver with a deinterleaver speed adapted to receive the interleaved data and to de-interleave the received interleaved data to thereby generate data essentially equivalent to the received data; and the interleaver inserting dummy data in the received data to transform the shape of the interleaver to effect a constant delay by adapting interleaver depth parameter (M) to be proportional with the interleaver line rate; and wherein interleaver input speed is adapted based on a change in the interleaver depth parameter (M) and the interleaver output speed, the interleaver line rate and the deinterleaver speed remain constant until transformation is completed.
