The bit synchronization detect is very important in openedloop timing recovery of all digital receivers.
位同步检测是实现全数字接收机开环定时恢复的关键技术。

In the system, we adopt a balance channel frequency offset structure, phase locked IF tracking technique and openedloop precorrection.
在系统结构上采用了平衡通道频率补偿技术、中频锁相跟踪技术和开环预校正技术。
