摘要： Described herein are implementations related to the generation of probe frames. In one implementation, a generated probe frame includes two symbols, where the two symbols are different. In one implementation, a first of the two symbols is a probe symbol and a second of the two symbols is a quiet symbol.

摘要： Described herein are techniques related to data communications using a data packet having at least one frame with a preamble for use over media having a high degree of non-stationary noise (e.g., impulsive noise). The described techniques employ a preamble with a structure having multiple transitions between the preamble sections. Each transition indicates the start of the upcoming frame. With the techniques described herein, if noise damages the transitions between such sections beyond recognition, the receiver can still determine the frame start time from the one or more of the undamaged transitions. Thus, the robustness of communications via the noisy media is significantly increased. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
摘要翻译：这里描述了与使用具有至少一个帧的数据分组的数据分组相关的数据通信的技术，前导码用于具有高度非平稳噪声（例如脉冲噪声）的介质。所描述的技术采用具有在前导码部分之间具有多个转换的结构的前同步码。每个转换指示即将到来的帧的开始。利用本文描述的技术，如果噪声破坏了这些部分之间的转换超过识别，则接收机仍然可以从一个或多个未损坏的转变确定帧开始时间。因此，通过噪声介质的通信的鲁棒性显着增加。提交本摘要的理解是，它不会用于解释或限制权利要求的范围或含义。

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 su bcarriers above 30 MHz can increase from 30db (-80-(-11O)) to 50db (-80-(-13O)). 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 increased, 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以上的运营商的信噪比可以从30db（-80 - （ - 110））增加到50db（-80 - （ - 130））。因此，通过改变最大传输PSD级别，在PSD掩码上应用上限，可用的子载波上的可用SNR的总和增加，从而增加可获得的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。
