摘要： In embodiments, an adaptive tone erasure technique is applied to orthogonal frequency division multiplexing (OFDM) communications, such as ECMA-368 standard ultra-wideband (UWB) communications. A transmitter obtains jammed sub-carrier information and calculates an erasure mask. The jammed sub-carriers are nulled before transmitting to a receiver. In accordance with the erasure mask, bits falling on the jammed sub-carriers are replaced by erasure bits before interleaving, keeping the interleaver block size constant notwithstanding variations in the number of the jammed sub-carriers. The receiver also obtains the jammed sub-carrier information and the erasure mask. After the receiver deinterleaves the constant size blocks, it decodes the data without the erasure bits. The transmitter may detect the jammed sub-carriers itself, or obtain the information from the receiver. The receiver similarly may detect the jammed sub-carriers itself, or obtain the information from the transmitter.
摘要翻译：在实施例中，自适应音调擦除技术被应用于正交频分复用（OFDM）通信，诸如ECMA-368标准超宽带（UWB）通信。发射机获得拥塞的子载波信息并计算消失掩码。在发送给接收器之前，阻塞的子载波是无效的。根据擦除掩码，在交织之前，落在被干扰的子载波上的比特被擦除比特所替代，保持交织器块大小恒定，而不管被干扰的子载波的数量如何变化。接收机还获得拥塞的子载波信息和擦除掩码。在接收器对恒定大小的块进行交织之后，它解码没有擦除比特的数据。发射机可以自己检测拥塞的子载波，或者从接收机获取信息。接收机同样可以检测自己的拥塞子载波，或从发射机获取信息。

摘要： An adjustable filter is responsive to a control signal to change a frequency response of the adjustable filter based on frequency spectrum information. 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. In one example, the frequency spectrum information includes a status of an internal secondary radio. The frequency spectrum information may also indicate a region of operation where 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.
