The article deals with the importance of modulation error ratio to cable digital video transmission system and its relationship with other related parameters.
本文讨论了MER调制误差比在有线数字电视传输系统的重要性及与其它相关参数的关系。
Relations between bit error rate and average received signal-to-noise ratio ( SNR) in AWGN channel were derived for three modulation modes defined by Bluetooth 2.0+ EDR new specification. The function expressions of packet retransmission probability and average received SNR of ACL packets were put forward.
分析了蓝牙2.0+EDR新规范定义的3种调制方式在AWGN信道下的位错误率与平均接收信噪比的关系,推导了ACL分组的重传概率与平均接收信噪比的函数表达式。
