message length中文什么意思

例句与用法

1. Server : client hello message length error
   服务器:客户端你好信息长度错误。
2. Keep message length to a minimum , particularly when sending to a group or attaching a file
   保存对讯息最小的长度，尤其是当寄送一个文件或附上一个档案的时候。
3. And then facing the problem of the channel estimation of the adaptive modulation system , we conclude out the channel estimation algorithms on maximum likelihood ( ml ) estimation and maximum a posteriori ( map ) estimation under the condition of flat fading channel and selective fading channel in detail . to meet flat fading channel , we simulate the relationship of the ratio between the error covariance in map estimation and ml estimation and pilot symbol message length . the conclusion can be drawn from these results
   接着，对自适应调制系统中的信道估计问题难点，详细推导了平衰落信道条件下和选择性衰落信道条件下最大似然( ml )估计和最大后验概率( map )估计算法，针对平衰落信道，我们仿真了map估计和ml估计的方差与导频符号长度的关系，仿真结果表明，错误方差受多谱勒频率的变化影响最大，并且对实际的自适应调制系统，导频符号长度的取值超过20个符号长度时， map信道估计明显优于ml信道估计。
4. And considering the practical adaptive modulation , when the value of pilot symbol message length is more than twenty symbol message length , map channel estimation is obviously superior to ml channel estimation . facing the qam constellation controllable adaptive modulation system , we go deep into the models , frame architecture , the constellation select for star qam and square qam , architecture implementation and so on . we elaborate on the slice decision of the square qam
   针对qam星座可调的自适应调制系统，深入研究了系统的模型、帧结构、星型qam星座和方型qam星座的选择、实现的结构等，分析了方型星座下的判决门限，并给出了判决门限的仿真结果。
