摘要： An adjustable filter is responsive to a control signal to change a frequency response of the adjustable filter based on at least one of a geographic location, frequency spectrum information, and a status of a secondary internal radio. The control signal may shift a center of the pass band from a first center frequency to a second center frequency and/or change a pass band bandwidth from a first bandwidth to a second bandwidth. A transmitter includes an adjustable filter responsive to a control signal and controller configured to select a frequency response of the adjustable filter by generating the control signal based on a geographical location. In one aspect, the geographical location indicates a region of operation of the receiver and the frequency response is selected in accordance with the region.

摘要： Embodiments describe reducing interference in a wireless communication network, including an ad hoc network. According to an embodiment, a method for reducing interference includes receiving a data packet and determining a channel quality level of the received data packet. The method further includes calculating a number of groups to divide the data packet into based on the channel quality level and determining a slot position within each group. The positioning of an acknowledgment channel within each group can be optimized to reduce the amount of overhead channels or to provide time to decode a traffic channel.

摘要： Method for reducing power consumption in a multimode device is disclosed. The multimode device includes a COMM1 component and a COMM2 component. In one aspect, a COMM1 component may be a UWB component and a COMM2 component may be a CDMA component. According to a disclosed embodiment, the time for a next scheduled COMM1 wakeup process to be performed by a COMM1 module is established. Thereafter, if the next COMM1 wakeup process is scheduled to be performed before the next COMM2 wakeup process, a COMM2 wakeup process is synchronized to be performed by a COMM2 module at the same time as the next COMM1 wakeup process. Following, when the time arrives for the COMM1 module to perform the next COMM1 wakeup process, the COMM2 module also performs the COMM2 wakeup process.
