In wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution of traditional delay estimation algorithms is inversely proportional to the bandwidth of the training signals used for channel probing. Considering that typical training signals have...

WLAN 802.11 (WiFi) and WPAN 802.15 (Bluetooth) operate in the same 2.4GHz ISM band. OFDM WLANs are designed to provide very high data rates, resilience to multipath and extended operating range. One of the main barriers to actually achieving the high data rates is the interference from the Bluetooth systems which is one of the main sources of...
