Transmitter Techniques for Multi-Carrier On-Off Keying

The IEEE 802.11ba Task Group is developing a wake-up radio standard which introduces a physical layer based on a signalling technique named Multi-Carrier On-Off Keying. This form of modulation is a hybrid between Orthogonal Frequency Division Multiplexing and On-Off Keying. It brings in both new challenges and possibilities. In this paper we present novel transmitter techniques that improve the performance, either by addressing some shortcomings or by exploiting some of the unique characteristics of Multi-Carrier On-Off Keying.
