Abstract
In most communication scenarios where the transmission time is short compared to the idle listening time for a data transmission, most power is consumed by the receiver. This brings up the need for a wake-up-receiver (WuRx) embedded in the system. This work presents a WuRx designed out of commercial components in order to investigate the needs of an WuRx embedded in a WPAN in a real environment setup including WLAN and LTE communication and considering interferer rejection. A system design is presented that fulfills all requirements and is designed with regard to enabling a duty cycle scheme for the reduction of the power consumption. Investigation of the duty cycling behavior is shown, technical difficulties are named and the resulting sampling rate and the power saving capability are analyzed.
