英语翻译
A receiver applies the FEC decoder to FEC-encoded data received for each source block
to recover that source block,where FEC-encoded data for a source block is any
combination of the source and repair symbols sent for that source block.The FEC
decoder is able to recover each source block fully,even if some packets containing FEC-
encoded data for that source block are lost,as long as enough FEC-encoded data for the
source block is received.Ideally,an FEC code has the property that the amount of FEC-
encoded data needed to recover a source block is the size of the source block,but for many practical FEC codes an additional small overhead of additional FEC-encoded data
beyond the source block size is needed to ensure high reliability decoding of the source
block.The source block size is chosen to be small enough that the FEC decoder can
decode a source block using available RAM in the mobile receiving device.
接收装置对每块接收到的FEC编码的数据源应用FEC解码器,以恢复数据源块.数据源块中FEC编码的数据是针对此数据源块所发送的数据源和修复符号的任意组合.就算源块中某些含有FEC编码数据的数据包丢失了,只要接收到此块中足够多的FEC编码的数据,FEC解码器可以完全恢复此数据源块.理想情况下,FEC代码的特点是恢复一个数据源块所需的FEC编码的数据量即为数据源块的大小.但是很多实际的FEC代码中,除了确保高度可靠地解码数据源块所需的数据量外,还有少量额外的FEC编码的代码存在.数据源块的大小被设定为小到足够移动接收设备里可用的RAM来使用FEC解码器去解码一个数据源块.
再问: 谷歌翻译 就不要拿来了 好么?
再答: 你看不懂吗?我一个字一个字翻译的。 我从来不用翻译器。
再问: 好吧 我看错了 我读了下 确实可以。 就你了
再答: 谢谢...望采纳为满意答案~
