在相干光正交频分复用系统中，本文提出了一种新型的基于循环前缀和虚载波的盲频偏估计方法。
A new blind frequency offset estimation method based on cyclic prefix and virtual subcarriers in coherent optical orthogonal frequency division multiplexing (CO-OFDM) system is presented.
编译器可以使用间接调用执行优化，如提升循环外虚方法地址的加载。
The compiler can perform optimizations with indirect calls such as hoisting the load of a virtual method address out of a loop.
