Abstract

A system (702) and method for detecting an impulse radio signal obtains a template pulse train (730) and a received impulse radio signal (708). The system (702) compares the template pulse train (730) and the received impulse radio signal (708) to obtain a comparison result (712). If the comparison result passes the threshold check, the system (702) locks on the received impulse radio signal (708). The system (702) may also perform a quick check, a sychronization check, and/or a command check of the impulse radio signal (708).
