摘要： A method of powerline communications including a first node and at least a second node on a powerline communications (PLC) channel in a PLC network. The first node sends a physical layer (PHY) data frame on the PLC channel including a preamble, a PHY header, a MAC header and a MAC payload. The MAC header includes a Cyclic Redundancy Check (CRC) field (MH-CRC field). The second node receives the data frame, parses the MAC header to reach the MH-CRC field, and performs CRC verification using the MH-CRC field to verify the MAC header. If the CRC verification is successful, (i) the second node parses another portion of the MAC header to identify a destination address of the data frame and (ii) to determine whether the data frame is intended for the second node from the destination address.

摘要： Systems and methods for designing, using, and/or implementing communications in beacon-enabled networks are described. In various implementations, these systems and methods may be applicable to power line communications (PLC). For example, a method may include identifying one of a plurality of orthogonal superframes. The identified superframe may include beacon slots and contention access period (CAP) slots. The beacon slots may follow a sequence of two or more frequency subbands, and the CAP slots may follow the same sequence of two or more frequency subbands. Also, the sequence of two or more frequency subbands may be distinct from other sequences of two or more frequency subbands followed by other beacon slots and CAP slots within others of the plurality of available superframes. The method may then include communicating with another device using the identified superframe.

摘要： A system and method for communicating in a power line communications (PLC) network using Orthogonal Frequency-Division Multiplexing (OFDM) symbols. Pilot tones are carried by the OFDM symbols according to a predetermined pattern. A receiving device identifies pilot tones on each frequency. A group of previously received pilot tones on a selected frequency are filtered to generate a channel estimate for a tone on the selected frequency in a new symbol. The channel estimates on two different frequencies within an OFDM symbol may be interpolated to determine a channel estimate for a third frequency with the OFDM symbol.

摘要： Embodiments of the invention provide time-domain link adaptation in power line communications. In one embodiment, the cyclic prefix length and position is adjusted with an OFDM symbol to overlap a periodic impulse noise pulse, thereby allowing the data carried in the symbol to be detected at a receiver. The cyclic prefix may be adjusted to provide a pattern that yields an integer number of OFDM symbols in one zero crossing period. The data rate used for the symbols overlapping the zero-crossing period may be zero or very low. A high data rate may be used for symbols outside the zero-crossing period because those symbols will not be affected by the periodic impulse noise.
摘要翻译：本发明的实施例提供了电力线通信中的时域链路自适应。在一个实施例中，循环前缀长度和位置用OFDM符号调整以与周期性脉冲噪声脉冲重叠，从而允许在接收器处检测符号中携带的数据。可以调整循环前缀以提供在一个零交叉周期中产生整数个OFDM符号的模式。用于与过零周期重叠的符号的数据速率可以为零或非常低。由于这些符号不受周期脉冲噪声的影响，因此高数据速率可用于过零周期以外的符号。

摘要： Embodiments provide a method for determining the number of parity bytes that are added by a Reed-Solomon encoder. The number of parity bytes are equivalent to the error correcting capability of the Reed-Solomon code. The number of parity bytes is based on the payload length or the information block size used in the Reed-Solomon encoder. Other factors may also be used to make this choice.
