摘要

基于W-CDMA FDD(宽带码分多址，频分双工)的编码/复用方案，选择了CRC(循环冗余校验)辅助提前停止方法作为W-CDMA节点b中Log-MAP(对数最大后验)turbo解码器的硬件实现方法，并对解码器结构进行了修改，以有效地整合CRC辅助方法。我们改进的解码器以可忽略不计的成本和没有性能下降，更有效地工作。

Hardware implementation of Log-MAP turbo decoder for W-CDMA Node B with CRC-aided early stopping

Based on the coding/multiplexing scenario specified for W-CDMA FDD (wideband-code division multiple access, frequency division duplex), CRC (cyclic redundancy check)-aided early stopping method is chosen for hardware implementation of the Log-MAP (logarithm-maximum a posteriori) turbo decoder for use in W-CDMA Node B. Modifications to decoder structure for efficient incorporation of the CRC-aided method are proposed. With negligible cost and no performance degradation, our modified decoder works more efficiently.
