当存在同步错误时，子载波之间的正交性遭到破坏，从而引起严重的载波间干扰，使解调性能大大下降。
When a synchronization error exists, the orthogonality between sub-carriers can't be maintained, serious inter-carrier interference is introduced and demodulation performance will be degraded greatly.
为了使调制解调器有时间在准备回叫时进行重置，客户端将延迟操作。
The client is delaying in order to give the modem time to reset itself in preparation for callback.
在该系统中，通过采用新的温度信号解调方法，使系统的信噪比获得提高的同时，还提高了系统的测温灵敏度。
In this system we improve the ratio between signal's power and noise's power together with the sensitivity of the system by a new temperature signal demodulating method.
