SIGNAL ENCODING AND DECODING METHODS, DEVICE AND SYSTEM

摘要

The present invention relates to a wireless signal decoding method, used for decoding an electrical signal converted from a wireless signal, the decoding method comprising the following steps: the duration of each level of the electrical signal is recorded; an average value of m maximum durations and an average value of n minimum durations are calculated, m and n being positive integers and respectively determined with reference to a distribution ratio value of a first binary bit value and a second binary bit value in the data; a determining length of time is calculated according to the first average value and the second average value; the duration of each level is compared with the determining length of time, and the binary bit value represented by the level is determined according to a comparison result; the various binary bit values are integrated to restore the data represented by the electrical signal.
