摘要： A wireless communication apparatus in a hierarchically coded modulation system can use error control mechanisms generated during decoding of base layer information to predict a probability of successful demodulation of enhancement layer information. Performance in the demodulation of the base layer correlates to performance in the demodulation of the enhancement layer. The receiver can determine whether to attempt demodulation of temporally correlated enhancement layer data based in part on the predicted probability of success. If the receiver determines not to demodulate the enhancement layer, the receiver can power down the enhancement layer demodulator, or otherwise minimize the power expended in the enhancement layer demodulator.
摘要翻译：分级编码调制系统中的无线通信装置可以使用在解码基层信息期间产生的误差控制机制来预测增强层信息的成功解调的概率。基层解调性能与增强层解调性能有关。接收机可以部分地基于预测的成功概率来确定是否尝试对时间相关的增强层数据的解调。如果接收机确定不解调增强层，则接收机可以将增强层解调器断电，或以其他方式最小化增强层解调器中消耗的功率。
