A system and method is provided for interleaving data in a communication device. The system includes a memory that stores blocks of data to be interleaved. A write module is configured to receive a burst of data and write blocks of data from the burst into the memory. The write module is configured to provide control information, including a rolling burst counter and a burst profile bank identifier for each block. If interleaving is activated, the control information includes information pertaining to how the read module should interleave the block. If interleaving is not activated, the control information includes the byte length size of the burst. A read module reads blocks of data from memory in either an interleaved fashion or a non-interleaved fashion in accordance with the control information.
