ABSTRACT:
A method and system for interleaving in a parallel turbo decoder enables the use of economical dual-port memory. According to the method, an incoming coding block is divided into a plurality of sub-blocks (step1005). Each sub-block is divided into a plurality of windows (step1010). An inter-window shuffle is then performed within each sub-block (step1015). Each window is divided into two sub-windows (step1020). Then an intra-window permutation is performed within each sub-window (step1025).
