摘要： An OFDM communication system is described that allows different values of D in a single domain where nodes are operating in different portions of frequency bands. For the power-line medium, G.9960 has defined two overlapped baseband bandplans, 50MHz-PB and 100MHz-PB. In this exemplary scenario, the level of frequency diversity is different depending on the bandplan, hence providing different header decodibility if D is fixed to 1. If D is fixed to 2, then it increases reliability for the narrowband devices, but may also unnecessarily increase overhead for the wide-band devices. An exemplary aspect is therefore directed to techniques to accommodate different repetitions schemes (D = 1,..., DMAX and H = I,..., H MAX ) in a single domain, and still allow devices to communicate with one another where D MAX and H MAX can be larger than 2.

摘要： A system or method in an OFDM communication environment includes transmitting, by a transmitter, and/or receiving, by a receiver, a frame that includes one or more preamble symbols, one or more header symbols, a plurality of data symbols, and a plurality of probe symbols. The probe symbols are predefined symbols that do not carry user data and are generated by modulating a predefined pseudo-random bit sequence (PRBS). A frame header, communicated in the one or more header symbols, includes one or more bit fields that indicate that the frame includes N probe symbols, wherein N is an integer greater than 1, and wherein the plurality of probe symbols are transmitted or received after the one or more header symbols and before the plurality of data symbols.

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： A network, such as wired and/or wireless LAN, is configured to have both point-to-point and point-to-multipoint connections. The point-to-multipoint connection(s) is used to communicate information between a plurality of the stations (or modem, or transceivers) in the network, whereas the point-to-point connection(s) are used to communicate information between only 2 stations in the network with the ability to, for example, maximize performance (rate/reach/BER/latency/etc) between those two stations. A master station allocates one or more frequency bands to the various point-to-multipoint and point-to-point connections.

摘要： The ability to accurately and efficiently calculate and report communication errors is becoming more important than ever in today’s communications environment. More specifically calculating and reporting CRC anomalies in a consistent manner across a plurality of communicatons connections in a network is crucial to accurate error reporting. Through a normalization technique applied to a CRC computation period (e.g., the PERp value), accurate error identification and reporting for each individual connection can be achieved.

摘要： With the current initialization procedures defined in the VDSL and ADSL standards, even though the xDSL system could operate in Showtime in an impulse noise environment where symbols are being corrupted, the transceivers would not be able to reach Showtime because initialization would fail due to initialization message failure. Through the use of an improved initialization procedure for communication systems, operation in environments with higher levels of impulse noise is possible.
摘要翻译：使用VDSL和ADSL标准中定义的当前初始化过程，即使xDSL系统可以在符号被破坏的脉冲噪声环境中在Showtime中运行，收发器将无法到达Showtime，因为初始化将由于初始化消息而失败失败。通过使用改进的通信系统的初始化过程，可以在具有较高等级的脉冲噪声的环境中进行操作。

摘要： A stable Low Power Mode (LPM) for multicarrier transceivers is described that at least provides transmit power savings while enabling receiver designs that can easily operate without the detrimental effects of fluctuating crosstalk. In one exemplary embodiment, the LPM achieves power savings by reducing the number of used subcarriers without actually performing a power cutback on those subcarriers, thereby allowing a receiver to measure the SNR or noise levels and determine the crosstalk noise on the line regardless of a crosstalking modem being in a LPM or not.

摘要： Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.

摘要： There is a need for a forensic diagnostic capability to facilitate a greater understanding of why xDSL transceivers are subject to otherwise inexplicable service interruptions during Showtime (steady state data transmission mode). In certain exemplary embodiments, diagnostic data from a previous Showtime is stored and then communicated to another transceiver and/or reported (or communicated) to a management entity. The stored diagnostic data can be used to determine why the service interruption occurred. In other embodiments, one or more portions diagnostic data from a last Showtime are stored. In additional embodiments, this diagnostic data is collected immediately prior to exiting Showtime and/or retraining (the "last" data collected prior to exiting Showtime and/or retraining). Alternatively, or in addition, the diagnostic data can be collected during a current Showtime using a sliding window that covers the most recently received signals and communicated to another transceiver and/or a management entity during the current Showtime.

摘要： By utilizing Reed-Solomon erasure decoding algorithms and techniques, the system is able to perform error detection for the case where the number of bytes received in error exceeds a correcting capability of a decoder. The error detection can be used, for example, to determine whether a codeword is decodable, and whether the retransmission of data is necessary. The retransmission can be accomplished by assembling a message that is sent to another modem requesting retransmission of one or more portions of data, such as one or more codewords.
摘要翻译：通过利用Reed-Solomon擦除解码算法和技术，系统能够对错误接收的字节数超过解码器的校正能力进行错误检测。例如，可以使用错误检测来确定码字是否可解码，以及是否需要重传数据。重传可以通过组合发送到另一个调制解调器的消息来实现，该消息请求重发一个或多个数据部分，例如一个或多个码字。
