Apparatuses, systems and methods for transmitting and receiving modulated
impulse radio signals. An
impulse radio receiver includes a time base, a precision
timing generator, a template generator, a
delay, first and second correlators, a data
detector and a time base adjustor. The time base produces a periodic timing
signal that is used by the precision
timing generator to produce a timing trigger
signal. The template generator uses the timing trigger
signal to produce a template signal. A
delay receives the template signal and outputs a delayed template signal. When an
impulse radio signal is received, the first correlator correlates the received impulse
radio signal with the template signal to produce a first correlator output signal, and the second correlator correlates the received impulse
radio signal with the delayed template signal to produce a second correlator output signal. The data
detector produces a
data signal based on at least the first correlator output signal. The time base adjustor produces a time base adjustment signal based on at least the second correlator output signal. The time base adjustment signal is used to synchronize the time base with the received impulse
radio signal.
