“…As the comparison in (Oetting, 1979) shows, on-off-keying (OOK) is the simplest modulation scheme for digital radio transmission. A tuned RF receiver is one of the simplest architectures (Griggs, 2012).…”

Abstract. Power consumption in wireless networks is crucial. In most scenarios the transmission time is short compared to the idle listening time for data transmission, the most power is consumed by the receiver. In low latency systems there is a need for low power wake-up receivers (WuRx) that reduce the power consumption when the node is idle, but keep it responsive. This work presents a WuRx designed out of commercial components to investigate the needs of a WuRx when it is embedded in a Wireless Personal Area Network (WPAN) system in a real environment setup including WLAN and LTE communication and considering interferer rejection. The calculation necessary for the attenuation of those interferers is explained in detail. Furthermore, a system design is presented that fulfills the requirements for this environment and is build from off-the-shelf components.

“…Other low-power receivers use FSK modulation [9,[12][13][14][15], which is slightly more interferer-robust than OOK modulation [27]. Because the frequency reference needs to be stable, most FSK receivers use power consuming PLLs [9].…”

“…The higher the complexity, the more stringent the receiver and transmitter requirements on various performance parameters, for example error vector magnitude (EVM), phase noise and I/Q imbalance. Figure 3.1 shows the complexity of many digital modulation types that are discussed in [27]. When comparing the modulation complexity shown in figure 3.…”

“…When comparing the modulation complexity shown in figure 3. [27]. OK-QPSK is also known as O-QPSK. with the state of the art receivers summarized in tables 3.1 and 3.2, it can be noted that the reported low-power receivers use, indeed, the two least complex demodulation schemes: envelope detector based OOK and non-coherent FSK demodulation.…”

The paper examines the application of pulse-compression techniques used in radar systems to FSK and PSK detection. Noncoherent FSK and differentially coherent PSK detection schemes using a mixer followed by a pulse-compressor matched filter are investigated. The mixer-PCMF combination, which acts as a predetector processor, converts the FSK modulation into pulse-position modulation and the PSK modulation into pulse-polarity modulation. A microprocessor-supervised experimental system for the FSK and DPSK detection schemes has been constructed and used to perform error-rate measurements for both schemes in the presence of additive white Gaussian noise and carrier interference. Some practical imperfections were also examined to determine their effect on system performance. The results show that both detection schemes are worthy of further consideration for use in the field of digital data communication, especially in HF communication applications, where carrier interference is a common impairment.
