ABSTRACT:
A method and system are disclosed for generating and detecting secure UWB or relatively small time domain impulsive communications signals. A transmitter generates a sequence of at least three pulses having a predetermined template, and the pulses are generated in a predetermined sequence anywhere within a series of predetermined time intervals. A receiver detects the sequence of pulses within the predetermined intervals by convolving the predetermined template with the received signal. The information represented by the detected pulses is preferably used for secure communications.
