Abstract
A system and method for reliable transmission of information using asynchronous transfer mode (ATM) through a noisy transmission path such as a wireless or satellite transmission link. To efficiently adapt ATM to such wireless links requires the ability to discern ATM cell addresses in a high noise environment. The system and method provides multiple redundant addressing to reduce or eliminate misrouting of ATM cells transferred through such a noisy transmission link. The multiple redundancy addressing realizes multiple virtual circuits to the same destination. The multiple redundant addresses for the circuits are within the error space of a principal address used for actual transmission. Thus, the most probable error patterns occurring in the ATM address field will change the principal address to a redundant address to the same destination, thus avoiding misrouting of the ATM cell.
