Patent ID: 7352771

Claim:
A data collision detection device for decoding received signals from data transmitters, comprising: a means for de-modulating at least one modulated carrier signal corresponding to a received signal from at least one data transmitter; and a module operatively coupled with the means for de-modulating, the module including a means for decoding a recovered subcarrier signal recovered from the means for de-modulating, the means for decoding the recovered subcarrier signal being capable of interpreting signal transitions in the recovered subcarrier signal and being capable of detecting a data collision within the recovered subcarrier signal in the presence of a plurality of modulated carrier signals detected in the recovered subcarrier signal; wherein the means for decoding a recovered subcarrier signal includes a means for counting a number of transitions before and after a bit-center of the recovered subcarrier signal; and wherein the means for decoding a recovered subcarrier signal is configured to detect a data collision when the number of transitions before the bit-center and the number of transitions after the bit-center are substantially equal.
