A novel orthogonal modulation format for Body Area Networks

Body Area Networks (BAN) are the next generation of Medical monitoring networks. They are being designed and developed to provide health care to patients on the move. However, there are multiple issues that are required to be addressed before they are deployed. The demand for higher data rate in BANs, for carrying the patient's medical information and enabling the streaming of data intensive services, has led to widespread research in this area. This paper suggests a novel orthogonal modulation technique using Hermite pulses that are not only fading resistant, due to their bipolar signaling, but also able enough to provide relatively better performance compared to other available modulation techniques like pulse position modulation. Simulation results depicting the symbol and bit error rate graphs prove the performance and suggest the efficiency of the modulation technique.
