Design and Realization of 8:12 Balanced Modulation Codes 12平衡调制码的设计与实现
With the balanced TE and TM modes, the measured results show that the TE-TM phase-difference modulator of the CPM can be used to realize good optical circular-polarization modulation. 在均衡了波导中TE模与TM模的基础上,实验表明,器件的TETM相位差调制器部分实现了很好的光波圆偏振调制输出特性。
The two dimensional orthogonal balanced modulation system of Walsh function has been introduced. 提出了二维Walsh函数正交平衡调幅制。
Because the group velocity dispersion ( GVD) can be balanced by self phase modulation ( SPM) in soliton system, optical solitons maybe become the ideal message carrier in long distance communication. 由于在孤子系统中群速度色散和自相位调制效应可以相互抵消,因此孤子通信被认为是长距离传输的理想方式。
