- Abstract
- The use of duty-cycled ultralow-power wake-up
receivers (WRxs) can significantly extend a node lifetime in
low-power sensor network applications. In the WRx design, both
the low-power operation of the WRx and the wake-up beacon
(WB) detection performance are of importance. We present a
system-level analysis of a duty-cycled WRx design, including an
analog front end, a digital baseband, the WB structure, and the
resulting WB detection and false-alarm probabilities. We select a
low-power WRx design with about two orders of magnitude lower
power consumption than the main receiver. The associated cost is
an increase in the raw bit error rate (BER), as... (More) - The use of duty-cycled ultralow-power wake-up

an increase in the raw bit error rate (BER), as compared with the
main receiver, at the same received power level. To compensate,
we use a WB structure that employs spreading. The WB structure
leads us to an architecture for the digital baseband with high
address-space scalability. We calculate closed-form expressions for
detection and false-alarm probabilities. Using these, we analyze
the impact of design parameters. The analytical framework is
exemplified by the minimization of the WB transmit energy. For
this particular optimization, we also show that the obtained re-
sults are valid for all transmission schemes with an exponential
relationship between the signal-to-noise ratio and the BER, e.g.,
the binary orthogonal schemes with noncoherent detection used in
many low-power applications. (Less)
