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： Methods systems and devices are provided for coordinating forward link blanking and/or power boosting in wireless communications systems. Some embodiments include two or more bandwidth systems. The bandwidth of one bandwidth system may overlap with the bandwidth of another bandwidth system. This overlap may create interference. Coordinating forward link blanking and/or power boosting may aid in reducing the impact of this interference. Some embodiments utilize flexible bandwidth and/or normal bandwidth systems. Flexible bandwidth systems may utilize portions of spectrum that may not be big enough to fit a normal waveform though some embodiments may utilize flexible waveforms that utilize more bandwidth than a normal waveform.
