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

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 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)
