match channel造句

• If no errors occur in it , the parity check part itself can retrieve the information by invertible process . if errors occur , the parity check part will be combined with the previously received information part to build an error - correction code , and try to recover the information . this kind of harq can match channel states very well
  该harq将信息码字和校验码字分开传送，信道状态较好时只传送信息码字；信道变差时才要传送校验码字，校验码字可单独或与信息码字一起将信息恢复出来，因此这种结构对信道有较好的适应性。
