Abstract

An apparatus and system for decoding colliding data transmissions utilizing an at will transmission protocol is disclosed. An apparatus for decoding an analog signal includes an input terminal, a data bus, a first decoder connected to the input terminal and data bus, configured to receive an analog signal, decode the signal into a first message and output the message to the data bus, a second decoder connected to the input terminal and data bus and configured to receive an analog signal, determine whether the analog signal includes a second message, decode the signal into a second message and out put the message to the data bus. A microprocessor operatively connected to the first and second decoders directs the second decoder to search for a colliding second transmission immediately after the first decoder has begun to decode a first transmission. If colliding second signal captures the receiver as the first transmission is decoded, the second decoder decodes and outputs the second message intact. A method for saving one of two colliding signals includes the steps of: (1) using a receiver to receive signals transmitted by a plurality of transmission units; (2) using a first decoder to decode a first signal; (3) directing a second decoder to search for a second transmission as the first signal is decoded by the first decoder; and (4) decoding the second received signal with the second decoder.
