Patent ID: 7414522

Claim:
A method for decoding first and second signals and each signal includes a plurality of bits, through the use of a controller, wherein the first signal is generated by a tire pressure monitoring (TPM) system and the second signal is generated by a remote keyless entry (RKE) system, the method comprising: receiving the signal having the plurality of bits for each of the first and second signals, wherein the plurality of bits have a format that includes a preamble section, a header section, and a data section for each of the first and second signals; generating a received signal strength indicator (RSSI) signal based on the first and second signals; measuring bits of the preamble section and the header section for each of the first and second signals; determining a first data bit threshold based on the measured preamble section bits and the header section bits for each of the first and second signals; storing the first data bit threshold in a look-up table of the controller for each of the first and second signals; measuring a first data bit of the data section for each of the first and second signals; comparing the measured first data bit to the first data bit threshold for each of the first and second signals; and determining a logic state of the first data bit based on the comparison between the measured first data bit and the first data bit threshold for each of the first and second signals.
