Performance of the ETSI SmartBAN system in the interfered IEEE 802.15.6 channel

The ETSI TC SmartBAN defined system is designed for body area networks supporting both on-body links and links to implanted devices. The system operates at the 2.4 GHz ISM band, where there are also other wireless radio systems, such as Bluetooth and WiFi. The SmartBAN system simulation model has been created to Matlab and the system performance was studied in the IEEE 802.15.6 channel model 3 with a measurement based interference model. The interference model is based on the measurement campaigns carried out in the Oulu university hospital. By using these simulation models, comparative analysis between BCH encoding schemes (127,113) and (36,22) on the system performance was carried out. It is shown that a higher coding rate has better performance in the presence of interference but it needs a repetition method to gain an acceptable frame error rate.
