A system and method for decoding signals from a tire pressure monitoring (TPM) system and a remote keyless entry (RKE) system includes determining a signal strength of the signal. The method also includes evaluating at least a first bit and the signal strength of the signal. The method further includes determining a first bit threshold based on the evaluated first bit and the signal strength. The method includes storing the first data bit threshold in a memory of the controller and determining a logic state of a second bit of a signal based on the first data bit threshold.
