RTP defines simple encapsulation of streaming media data, without error checking and loss packet retransmission. So it has high transmission efficiency, low delay, and it offers sequence number and timestamp for receiver to reconstruct and synchronize the data.

RTP对流媒体数据进行简单的封装,不进行错误检测和丢包重传,因此传输效率高、延时小,而且它提供了序列号和时间戳以便接收端进行数据重组和同步。

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。
