TWO-DIMENSION INTERLEAVING DEVICE AND METHOD

摘要

PURPOSE: A two-dimension intereleaving device is provided to maximize a minimum distance by preventing a component coder from being reset at a zero state. CONSTITUTION: A two-dimension intereleaving device comprises a plurality of address generators(711-71N), a controller(721) and a selector(731). Each of the address generators(711-71N) generates a read address according to a predetermined interleaving rule in an address generation region of a corresponding group. The controller(721) controls multiplexing of the selector(731), and the selector(731) selectively outputs the read addresses from the address generators(711-71N) under the control of the controller(721). The read address thus selected is used to read input frame data sequentially stored in an interleaver memory.
