    摘要: A method for network coding includes generating a message matrix, where each column of the message matrix corresponds to one of K message packets and each element in a column of the message matrix corresponds to one of the symbols of the corresponding message packet. The method further includes generating a network code matrix to map the K message packets to N encoded packets, where any combination of K columns of the network code matrix is linearly independent and N is greater than K. The method also includes multiplying the message matrix by the network code matrix to generate a transmission matrix, where each column of the transmission matrix corresponds to an encoded packet for wireless transmission.

    摘要: A method for network coding using a near-maximum distance separable linear network code includes generating a message matrix where each column of the message matrix corresponds to one of K message packets and each element in a column of the message matrix corresponds to one of the symbols of the corresponding message packet. The method also includes generating a network code matrix to map the K message packets to N encoded packets, where any combination of K+1 columns of the network code contains at least K columns that are linearly independent. Further, the method includes multiplying the message matrix by the network code matrix to generate a transmission matrix, where each column of the transmission matrix corresponds to an encoded packet for wireless transmission.

    摘要: A method for decoding linear network codes that includes receiving a plurality of packets from an ererror detector and generating a matrix out of the plurality of packets where elements of each column of the matrix correspond to symbols of the plurality of packets. Then decoding across each row of the matrix using only the symbols with highest associated reliability values to obtain a decoded matrix, where each column of the decoded matrix corresponds to a message packet.
