Low-PAPR Multi-channel OOK Waveform for IEEE 802.11ba Wake-up Radio
The peak-to-average-power ratio (PAPR) of the frequency domain multiplexed
wake-up signals (WUSs) specified in IEEE P802.11ba can be very large and
difficult to manage since it depends on the number and allocation of the active
channels, and the data rate on each channel. To address this issue, we propose
a transmission scheme based on complementary sequences (CSs) for multiple WUSs
multiplexed in the frequency domain. We discuss how to construct CSs compatible
with the framework of IEEE P802.11ba by exploiting a recursive Golay
complementary pair (GCP) construction to reduce the instantaneous power
fluctuations in time. We compare the proposed scheme with the other options
under a non-linear power amplifier (PA) distortion. Numerical results show that
the proposed scheme can lower the PAPR of the transmitted signal in frequency
division multiple access (FDMA) scenarios more than 3 dB and yields a superior
error rate performance under severe PA distortion.Comment: To appear in IEEE GLOBECOM'1
