A Study on SmartBAN Physical Layer Applying Multi-Level PSK Modulation

An Internet of Medical Things (IoMT) system has attracted attention. This research provides a study on an ETSI Smart Body Area Networks (SmartBAN), as one of the IoMT systems, physical layer (PHY) applying multilevel modulation. Specifically, comparative evaluation is performed to see how much packet error rate (PER) changes by changing the modulation scheme of the SmartBAN PHY from GFSK to several multi-level PSKs. Computer simulation shows that the multi-level PSK modulation is also useful in the wearable wireless body area networks (WBAN) channel model. In addition, it is shown how much the symbol rate can be improved with respect to the available frequency band. From these results, it is examined whether multi-level PSKs can be used for SmartBAN PHY by calculating the link budget and the receiver sensitivity.
