摘要： There are several exemplary ways to more efficiently communicate an out-of-domain seed to a receiver—in a first technique, the seed can be indicated in the header portion or data portion of a packet. For example, the header portion of the packet could contain one or more bit fields that indicate the value of the LFSR seed used for the preamble portion of the packet. The receiver would learn the out-of-domain seed after receiving a first out-of-domain packet and decoding the header portion of that packet. After learning the out-of-domain seed, the receiver could send a packet indicating the value of the out-of-domain seed to the local master. The local master could then transmit the value of the out-of-domain seed in the header portion or data portion of a local MAP frame.

摘要： Adjusted maximum transmit PSD levels have an effect on the SNR. If the ADC noise is assumed to be the limiting factor, then there can be a benefit for reducing the maximum transmit PSD level. For example, by lowering the maximum transmit PSD level from −50 dBm/Hz to −70 dBm/Hz results in an increase in SNR for subcarriers above 30 M Hz. The SNR for subcarriers above 30 MHz can increase from 30 db (−80-(−110)) to 50 db (−80-(−130)). Therefore, by changing the maximum transmit PSD level, applying a ceiling on PSD mask, the aggregate sum of the available SNR's over the available subcarriers is therefore increasing the obtainable OFDM data rate. In other words, a maximum transmit PSD mask can be used to lower the transmit PSD value of at least one subcarrier which results in an increase in SNR for at least one subcarrier.
摘要翻译：调整后的最大传输PSD电平对SNR有影响。如果ADC噪声被认为是限制因素，则可以有益于减少最大传输PSD电平。例如，通过将最大发射PSD电平从-50dBm / Hz降低到-70dBm / Hz，导致高于30MHz的子载波的SNR增加。 30 MHz以上的子载波的SNR可以从30 db（-80 - （ - 110））增加到50db（-80 - （ - 130））。因此，通过改变最大发送PSD电平，在PSD掩码上施加上限，可用的SNR在可用副载波上的总和因此增加了可获得的OFDM数据速率。换句话说，可以使用最大发射PSD掩模来降低至少一个子载波的发射PSD值，这导致至少一个子载波的SNR增加。

摘要： Among other things, a communication system comprising remote units, a reference timing source, a controller, a controller clock, and a remote unit clock. The remote units exchange radio frequency (RF) signals with mobile devices. The reference timing source is synchronized with a coordinated universal time (UTC) or a Global Positioning System (GPS). The controller clock is synchronized with the reference timing source and provides timing information to the controller. The remote unit clock is synchronized with the controller clock and provides timing information to a remote unit. The controller and the remote unit are configured to transmit time stamp messages to synchronize the controller clock and the remote unit clock, by avoiding contention between time stamp transmissions and baseband data transmissions or between time stamp transmissions of different remote units to the controller.

摘要： Using a known or later developed time domain equalizer coefficient training algorithm, a least square solution for the time domain equalizer coefficients is taken at a starting point and iteratively improved on. In particular, the improvement is directed towards maximizing number of bits per frame loaded over the time domain equalizer coefficient choice. This can be accomplished by maximizing capacity directly rather than setting a goal to shorten the channel and hoping that the capacity will be maximized as a result.
摘要翻译：使用已知或稍后开发的时域均衡器系数训练算法，在起点进行时域均衡器系数的最小二乘解，迭代改进。特别地，改进旨在通过时域均衡器系数选择来最大化每帧加载的比特数。这可以通过直接最大化容量来实现，而不是设定缩短通道的目标，并希望能力最大化。

摘要： A technique is provided that may be employed in multicarrier communications to improve the efficiency of error correction using symbol-oriented error correction methodologies, by reducing the number of error correction code symbols (102, 104 . . . ) that are received in error that result from a single channel error. More specifically, in this technique, bits from the symbols are allocated among the channels in such a way as to minimize the number of respective channels that are allocated bits belonging to more that one respective symbol during a respective transmission period.
