Because of the various application scenarios and use cases they make possible, Body Area Networks (BAN) have been investigated during the recent years by many academic and industrial communities. Among various technologies, Ultra Wide Band (UWB) was considered to be a good candidate for a physical layer in a BAN. Many propagation measurements have been conducted to study the wave propagation around the human body, and then design channel models. Our work aims at evaluating a UWB-Impulse Radio (IR) physical layer for BAN. This physical layer is based on Binary Phase Shift Keying (BPSK) and Binary Pulse Position Modulation (BPPM) modulations and it relies on the last IEEE 802.15.6 BAN channel models. This analysis presents the Bit or Symbol Error Rate (BER or SER) as a function of the signal to noise ratio (SNR). Computer simulations are conducted using IEEE 802.15.6 BAN channel models, and the system performances are investigated under coherent and noncoherent receivers.
