摘要： The present invention provides digital subscriber line noise mitigation techniques, and applications thereof. In an embodiment, the present invention provides a toolbox of methods and techniques for mitigating the effects of noise in xDSL systems. These methods and techniques are controllable and locatable at one or both ends of a DSL communication link (e.g., within a central office transceiver unit or a remote transceiver unit). These novel methods and techniques include: (1) per tone noise margin modification, (2) data framer constraints modification, (3) improved noise measurements; (4) more robust on-line reconfiguration processes, (5) worst case noise monitoring, (6) induced bit rate limitations, and (7) distortion noise mitigation. These methods and techniques are particularly useful for mitigating the effects of time-varying noise and impulse noise.

摘要： A method for selecting a mode of operation for at least two modems is described. First, a handshake procedure is performed in order to determine a set of possible modes of operation supported by said modems. From said set of possible modes of operation, a set of favorable modes of operation is derived. In case there exist two or more favorable modes of operation, a probing-based selection is performed that comprises evaluating respective performances of said favorable modes of operation. The favorable mode of operation with the best performance is selected as a resultant mode of operation.

摘要： The present invention relates to a method and a system for transmitting data in a xDSL communication system increasing the range of the communication link. The communication system may consist of any two communication devices that are connected together by a band limited communication line. According to the present invention for transmitting data in a bidirectional digital subscriber line (xDSL) communication system the communication system comprises a first communication device and a second communication device, both communication devices being connected by a communication line, wherein the first communication device is adapted to send data in upstream direction over the communication line in an upstream frequency spectrum and the second communication device is adapted to send date in downstream direction over the communication line in a downstream frequency spectrum, both communication devices are adapted to receive the data in the send frequency spectrum of the other communication device, and between the upstream frequency spectrum and the downstream frequency spectrum there is provided a guard frequency spectrum separating the upstream and the downstream frequency spectrums.

摘要： In a multiband detector (DET), sub-band reconstruction and distortion compensation is performed by a plurality of digital filters (FIR1, . . . , FIRk, . . . , FIRN) arranged in a single-input-multiple-output architecture. Each digital filter (FIRk) is coupled between one and the same input (RDA-I) whereto a distorted multiband signal (si) is applied and a respective output (RDA-Ok) whereto a reconstructed sub-band signal (sik) is applied. This multiband detector (DET) has a uniform architecture for each input-output path and can easily be adapted to changes in distortion of the multiband signal (si), even if these changes only affect a few sub-bands.
摘要翻译：在多频带检测器（DET）中，通过以单输入多输出架构布置的多个数字滤波器（FIR1，...，FIRk，...，FIRN）执行子带重建和失真补偿。每个数字滤波器（FIRk）耦合在施加失真的多频带信号（si）的同一输入（RDA-I）之间，并且施加了重构的子带信号（sik）的相应输出（RDA-Ok）。该多频带检测器（DET）具有用于每个输入 - 输出路径的均匀架构，并且可以容易地适应多频带信号（si）的失真的变化，即使这些改变仅影响几个子带。

摘要： In a multicarrier transmission system, a transmitter (T, T′) sends digital data packets (D) modulated on a set of carriers to a receiver (R, R′). A subset of the carriers constituting the set of carriers has frequencies (f1, f2, f3, f4) in predetermined frequency ranges (Amateur Radio Band) with high risk for being affected by narrowbanded interference (RFI), e.g. originating from radio amateur transmission. The data bits of the digital data packets (D) that are allocated to the subset of carriers having frequencies (f1, f2, f3, f4) within these predetermined frequency ranges (Amateur Radio Band), are allocated thereto in a redundant way. Via an allocation message (AM) communicated between the transmitter (T, T′) and the receiver (R, R′) both are aware of the redundancy in the bit allocations. The receiver (R, R′) is capable of measuring the amount of narrowbanded interference (RFI) that affects each carrier within the subset of carriers that may be affected thereby, and can re-combine data bits allocated to carriers in this subset which carry redundant data bits so that interference immunity is improved.
摘要翻译：在多载波传输系统中，发射机（T，T'）将在一组载波上调制的数字数据分组（D）发送到接收机（R，R'）。构成载波组的载波的一个子集具有在受窄带干扰（RFI）影响的高风险的预定频率范围（业余无线电频带）中的频率（f1，f2，f3，f4）。源自无线电业余传输。分配给这些预定频率范围（业余无线电频带）内的频率（f1，f2，f3，f4）的载波子集的数字数据分组（D）的数据位以冗余的方式分配给它们。通过在发射机（T，T'）和接收机（R，R'）之间通信的分配消息（AM）都知道比特分配中的冗余。接收机（R，R'）能够测量影响可能受影响的载波子集内的每个载波的窄带干扰（RFI）的量，并且可以重新组合分配给该载波中载波的载波的数据比特冗余数据位，从而提高抗干扰能力。
