The authors propose the use of a block orthogonal code to reduce the symbol error rate, and therefore improve the throughput, of wake-up radios used in sensor networks. Currently proposed wake-up radios that use, for example, on-off keying modulation focus on integrated circuit design for low power operation. However, they do not take error correction coding into account and therefore increase the error rates and reduce the node lifetime. They develop a system model to evaluate the throughput of their proposed scheme. They implement a simulation of this model and show that their approach significantly improves the throughput of these radios.
