Abstract

Synchronised On/Off keying (S-OOK) is a pulse modulation format where timing synchronisation pulses are embedded with each bit in the data stream resulting in a 1.5 pulse/bit format, but allowing for synchronisation and demodulation with a single block. In this reported work, the error ratio for S-OOK symbols received in a non-fading AWGN channel is analysed and a mathematical model aware of the physical parameters of a CMOS integrated prototype is introduced. Using this model, the S-OOK RX sensitivity is shown to be close to that of a high-threshold OOK RX for similar error-ratios but assuming perfect synchronisation.
