Abstract
Wireless Body Area Networks (BAN) are being developed to provide health care to patients on the move. Ultra wideband (UWB) is the most preferred candidate for the communication due to its high data rate and lower energy consumption characteristics. Since the data is transmitted wirelessly and narrowband systems are already using frequency bands within the UWB spectrum, a major concern here will be the interference from these existing narrowband wireless networks. The paper presents a novel narrowband interference mitigation method for UWB based Body Area Networks. The technique has been tested in the CM3 channel model for Body Surface communications. Comparison with other techniques demonstrate that the proposed method is far superior and immune to multiple narrowband interferences.
