1) timing and carrier phase deviation
定时偏移和载波相位误差
1.
In digital signal transmission systems, orthogonally multiplexed QAM system(OMQAM) is the most efficient transmission technique at present for non ideal channel, yet the problem is that this technique is quite sensitive to the timing and carrier phase deviation in the system.
在数字信号传输系统中，正交复用ＱＡＭ（ＯＭＱＡＭ）是目前最有效的一种抗信道失真传输技术，但它对系统的定时偏移和载波相位误差非常敏感。
2) carrier phase offset
载波相位偏移
1.
Estimating carrier phase offset and adjusting phase from demodulated signal(training sequence)makes it un- necessary to set phase-locked loop in receiver,thus decreasing the complexity of receiver in 16QA.
从已调信号(训练序列)中直接导出载波相位偏移量并进行相位校正,免去了在接收端设置锁相环,降低了16QAM通信系统接收端的复杂度。
3) Symbol timing and carrier frequency offset
符号定时和载波频率偏差
4) Ccarrier Phase Error Detection
载波相位误差检测
5) Carrier phase tracking error
载波相位跟踪误差
6) observation error for carrier wave
载波相位观测误差
