    摘要: A software-defined radio (SDR) system that operates under a plurality of wireless communication standards. The SDR system comprises a reconfigurable maximum aposteriori probability (MAP) decoder capable of being configured under software control to decode a received data block according to a select wireless communication standard and a reconfigurable interleaver associated with the reconfigurable MAP decoder. The reconfigurable interleaver comprises a reconfigurable interleaver core circuitry capable of being configured under software control to operate according to the selected wireless communication standard and a unified interleaver interface for coupling a defined set of control and bus signals from the reconfigurable MAP decoder to the reconfigurable interleaver core circuitry.
