Coexistence of UWB systems for body area networks in AWGN

The paper describes a coexistence study of IEEE 802.15.6 UWB devices with other UWB systems, in particular IEEE 802.15.4a (pico-nets) and IEEE 802.15.4f (RFID). At the time of writing this paper, IEEE 802.15.6 and IEEE 802.15.4f are in the last phase before publication. Hence, a brief summary of both PHYs is introduced. On the other hand, IEEE 802.15.6 UWB PHY includes IR-UWB and FM-UWB technologies. The IR-UWB transceivers for BANs are based on the transmission of a single and relative long pulse per symbol (new paradigm in UWB) or a concatenation or burst of short pulses per symbol (legacy), while FM-UWB transceivers are based on the concatenation of a CP-2FSK modulation and a wideband FM. Thus, coexistence between UWB devices becomes very important for reliable operation in medical applications.
