    • To perform erasure detection for an intermittently active transport channel with unknown format, a receiver determines an energy metric and a symbol error rate (SER) for a received block with CRC failure. The receiver computes uncorrelated random variables u and v for the received block based on the energy metric and SER, the estimated means and standard deviations of the energy metric and SER, and a correlation coefficient indicative of the correlation between the energy metric and SER. The receiver then evaluates the uncorrelated random variables u and v based on at least one decision criterion and declares the received block to be an erased block or a DTX block based on the result of the evaluation. The decision criterion may be defined based on a target probability of false alarm and adjusted based on another metric, such as a zero state bit, for the received block.
    • 为了对具有未知格式的间歇活动传输信道执行擦除检测,接收机确定具有CRC故障的接收块的能量度量和符号错误率(SER)。 接收机基于能量度量和SER,能量度量和SER的估计平均值和标准偏差以及表示能量度量与SER之间的相关性的相关系数,计算接收块的不相关随机变量u和v。 然后,接收机基于至少一个决策标准来评估不相关的随机变量u和v,并且基于评估结果将接收到的块声明为擦除块或DTX块。 可以基于目标误报率概率来定义判定标准,并且基于接收块的另一个度量(例如零状态位)进行调整。
