Abstract
This disclosure relates to method, device and system for detecting errors in a communication system. A signal is received from a transmitter at a receiver wherein the signal includes a data portion and a result of a hash function. The hash function is computed in part from a transmitter identification code. The receiver determines if the result of the hash function matches both the data portion and the transmitter identification code. The receiver discards the signal if the result of the hash function does not match both the data portion and the transmitter identification code of the transmitter.
