blind codes meaning in Chinese

编制盲底

This paper focuses on the blind code synchronization approach and spreading sequences estimation algorithm . the main results can be summarized as follows : 1 . both synchronous and asynchronous dsss / bpsk baseband signal models are established
本文重点是对盲码同步和扩频码序列估计的研究,主要的工作成果如下: 1 、分同步和非同步两种情况建立了dsss / bpsk基带信号模型,并介绍了二种非合作式扩频码序列估计和解扩的方案。
Moreover two types of non - cooperative sequences estimation and despreading schemes are introduced briefly . 2 . several usual blind code synchronization methods , including delay multiply ( sliding autocorrelation ) , maximum norm and average noise reduction approaches are summed up and analyzed by computer simulations
2 、总结和介绍了几种常用的盲码同步方法,包括延迟相乘(滑动自相关)法、最大范数法、平均降噪法等,并进行了计算机仿真和分析。
