Energy optimisation of an OOK transmitter using high-order orthogonal modulation
, 2018 International audienceIn this paper, we show that high-order orthogonal modulation can be used to optimize the power consumption of an energy efficient On-Off Keying (OOK) transmitter for short range wireless sensor applications. Our work is based on the
