A tire parameter sensing system ( 12 ) for a vehicle ( 10 ) having a tire ( 16 ) comprises a tire-based unit ( 26 ) associated with the tire ( 16 ) and including structure ( 70, 72 ) for sensing a parameter of the tire ( 16 ) and for transmitting a parameter signal ( 38 ) indicative of the sensed parameter. The parameter signal ( 38 ) having at least first and second different signal characteristics. The tire parameter sensing system ( 12 ) also comprises a vehicle-based unit ( 34 ) having a first receiving channel ( 116 ) for receiving at least portions of the parameter signal ( 38 ) that include the first signal characteristic and a second receiving channel ( 118 ) for receiving at least portions of the parameter signal ( 38 ) that include the second signal characteristic. A signal detection portion ( 120 ) of the vehicle-based unit ( 34 ) is responsive to the first and second signal characteristics for determining the sensed parameter of the tire ( 16 ).
