Answer Posted / vidhya
we can use a signal detection arrangeent which is an
arrangement including a receiver and an enveloped detection
arrangement. The receiver receives radio frequency signals
generated according to a predetermined wireless
communication protocol. The envelope detection arrangement
screens the radio frequency signals for a predetermined
signal which utilizes the predetermined wireless
communication protocol and has a predetermined envelope
sequence. Upon detection of the predetermined signal, the
arrangement transmits a further signal to a computing
device coupled thereto. The further signal is an
instruction for the computing device to execute a
predetermined action. It can be possible through Pulse
Envelope Demodulation method too with unique Digital Signal
Processing algorithms help to prevent false alarms while
differentiating between strong, weak, and interfering
signals.further the combiner is not frequency selective..
