Spread spectrum communication is the most efficient mode in the strong noise environment such as the coal mine.
扩频通信是矿井等强噪声环境中最有效的通信方式。
But when loops, several spread-spectrum radios and centre control unit (moving block system with 'centralized' structure) fail, the system can not be running in the ATC mode.
但是当环线、多个扩频电台、中央控制单元(“集中式”移动闭塞系统)等设备出现故障时，系统将无法工作在ATC模式下。
