Implication Radio Frequency signal discrimination manner

摘要

Solutions In order for the signal detection and discrimination system, to distinguish the FSK modulating signal and the ASK modulating signal, to correspond to signal type signal reception mode is changed. The 1st valve particularly, the number of pulses inside the signal is counted over the time window which is selected. When it is inside the range where the number of pulses inside the time window is effective, the signal is ASK irregularity, it understands that it is the possibility of having the arrival data in the signal. When the number of pulses is not inside the scope, pulse is considered noise or the data of the baud rate which differs. When there is no pulse in the data signal inside the time window, it understands that the data signal is FSK irregularity, the receiver is changed to FSK mode from ASK mode.
