... consensus is obtained by averaging the pairwise local time information in the di fferent network nodes. In most algorithms, only the current timing information is considered, resulting in a first-order ... obtained by using the information from the downlink signal, a low-complexity compensation technique for fine carrier frequency synchronization in the uplink is proposed. Many of the...

... propose in the sixth paper apower-efficient communication protocol (PCP) for inte- grated WWAN and WLAN. This protocol includes turning off the WLAN interface after it enters the idle state and using the ... using the paging channel of WWAN in order to wake up the WLAN interface when there is incoming long-lived multimedia data. Further, the proposed scheme is designed to avoid repeatedly tu...
