摘要： A system and method for de-interleaving data in a wireless receiver (116), wherein a single memory buffer (406) is coupled to a read/write unit (402) that performs both first and second de-interleaving operations. According to a first aspect of the invention, the read/write unit (402) performs the second de-interleaving operation as data is written to the memory buffer (406), and performs the first de-interleaving operation as data is read from the memory buffer (406). According to the second aspect of the present invention, the read/write unit (402) performs the first and second de-interleaving operations as data is read from the memory buffer (406).

摘要： A first radio frame of data from an input code block is sent downstream without being stored in the memory buffer (702). Accordingto a first embodiment of the present invention, the remaining ra dio frames from the code block are stored in the memory buffer (704). The first interleaving pattern can be applied as data is written to or read from the memory buffer (506). The stored radio frames are then read out as needed by the downstream processing. According to a second embodiment of the present invention, additional radio frames from the input code block may be stored in the memory buffer, and the remaining frames are discarded. The frames stored in the memory buffer are then readout as needed by downstream processing. The input code block is then recalculated by operation upstream from the first interleaver.
