The hardware in the system is simple, applicable and reliable, because intelligent components have been adopted and many functions can be achieved by software. Even if the code rates deviate from the designed value (300 baud/s) in 50 times, the remote signals can still be exactly received by the code rate measuring with software. The elash among remote signals from multiple spots is completely eliminated by checking their priorities with software.展开更多
