IEEE 802.15.6 DPSK Impulse-Radio Ultra-Wideband Physical Layer: Receiver Architectures and Interference Performance

摘要

The paper analyses performances of the two lowest data rates of impulse-radio ultra-wideband DPSK physical layer of recently published IEEE 802.15.6 Body Area Networks standard. Two receiver architectures suitable for the reception of symbols with signal structure described in specification of this physical layer, namely duty-cycled sampling receiver and chirp receiver, are introduced. Then, performance of these receiver architectures are analyzed through probabilities of error in different phases of packet reception. Analysis has been performed in the presence of different types of interference; namely frequency modulated ultra-wideband, WiMax and other co-located IEEE 802.15.6 impulse-radio ultra-wideband devices.
