Amplitude-shift-keying (ask) radio-frequency (rf) signal decoding device and method thereof

Abstract

An amplitude-shift-keying radio-frequency (ASK RF) signal decoding method includes separating a low frequency and a high frequency from an ASK RF signal, which includes a pause section and a non-pause section, generating a divided signal by dividing the high frequency signal, counting the divided signal for the non-pause section of the low frequency signal, and decoding the ASK RF signal based on a result of the counting.

1 . An amplitude-shift-keying radio frequency (ASK RF) signal decoding method, comprising:
 separating a low frequency signal and a high frequency signal from the ASK RF signal including a pause section and a non-pause section;   generating a divided signal by dividing the high frequency signal;   counting the divided signal for the non-pause section of the low frequency signal;   decoding the ASK RF signal based on a result of the counting; and   generating decoded data, wherein when first decoding data is a first logic level, the step of generating the decoded data comprises:   decoding second decoding data of the first logic level as data output next to the first decoding data when the result of the counting is smaller than a threshold value; and   decoding third decoding data of a second logic level as the data output next to the first decoding data when the result of the counting is greater than the threshold value.
