Abstract Energy-detection is appealing for IEEE 802.15.4a receivers as it allows to exploit the ranging capabilities and the multipath resistance of impulse-radio UWB at a reasonable complexity. IEEE 802.15.4a receivers operate with interference created by uncontrolled piconets and an uncoordinated medium access control. Prior work showed that the performance of an energy-detection based receiver is greatly degraded in such scenarios. Hence, we present an interference mitigation algorithm based on statistical interference modeling for energy-detection receivers. This combines a low complexity architecture and robustness to interference. Our performance evaluation shows that our solution decreases the packet error rate significantly.
