摘要： In the present disclosure, several techniques are proposed to estimate the worst-case crosstalk noise and use it for bit-loading and SRA calculations so that fluctuating crosstalk when PET mode is enabled does not lead to system instability. One of the proposed techniques involves strategically placing some marker tones in the transmitters of the affecting lines. The noise floor may be inferred by interpolating the noise observed on these marker tones (tones that are always-on) and applying to the entire frequency band on the victim line. Another proposed technique involves periodically transmitting a set of marker symbols (fully loaded OFDM symbols), so that a victim channel can estimate the SNRs in a worst case crosstalk scenario.
摘要翻译：在本公开中，提出了几种技术来估计最坏情况的串扰噪声，并将其用于位加载和SRA计算，使得当启用PET模式时波动的串扰不会导致系统不稳定。所提出的技术之一涉及在影响线路的发射机中策略性地放置一些标记音调。可以通过内插在这些标记音上观察到的噪声（始终保持开启的音调）并将其应用于受害线上的整个频带来推断出本底噪声。另一种提出的技术涉及周期性地发送一组标记符号（完全加载的OFDM符号），使得受害信道可以在最坏情况的串扰情况下估计SNR。
