Interleaver pattern modification

摘要

The invention provides a method of interleaving a source data stream using an interleaver pattern in a transmitter. A mother interleaver pattern and an interleaver parameter are accessed. The mother interleaver pattern is modified using said interleaver parameter. Then, the modified interleaver pattern is applied in the transmitter for interleaving the source data stream. The interleaver parameter used by the transmitter for modifying said mother interleaver pattern differs from the interleaver parameter used simultaneously by at least one other transmitter that transmits data at the same time on the same channel. The invention further provides a corresponding deinterleaving method. By decorrelating the interleaver processes in the different streams, the inter-stream interference is reduced. <IMAGE>
