    • A method, apparatus and computer program product providing improved communication performance through network coding is presented. Coded packets are formed at a source node, the coded packets comprising a combination of original packets at the source node. The coded packets are transmitted to at least one destination node using an unreliable protocol. A reconstruction is formed based on received coded packets at the destination node, wherein when a number of received coded packets are equal to the number of transmitted coded packets the forming a reconstruction comprises forming a complete reconstruction and wherein when the number of received coded packets is less than the number of transmitted coded packets the reconstruction comprises forming a best attempt at reconstruction.

    • Embodiments of the invention present implementations for multiple access source coding (MASC). One embodiment presents an implementation directed at the lossless side-information case of MASC. Another embodiment gives an implementation of the general case MASC. One embodiment is a near-lossless implementation of MASC. In a two dimensional example, the invention provides a way to decode data pairs (x,y) from encoded individual data streams x and y. The present invention provides a solution that partitions the source code into optimal partitions and then finds a matched code that is optimal for the given partition. Embodiments of the present invention use Optimal Shannon, Huffman and Arithmetic Codes for the matched codes. Another embodiment of the present invention gives a method of finding near-lossless multiple access source coding.
    • 本发明的实施例提出了用于多址存取源编码(MASC)的实现。 一个实施例提出了针对MASC的无损侧信息情况的实现。 另一个实施例给出了一般情况MASC的实现。 一个实施例是MASC的近无损实现。 在二维示例中,本发明提供了一种从编码的单独数据流x和y解码数据对(x,y)的方法。 本发明提供了一种将源代码划分成最佳分区然后找到对于给定分区是最佳的匹配代码的解决方案。 本发明的实施例使用用于匹配码的Optimal Shannon,Huffman和算术码。 本发明的另一个实施例给出了一种找到近无损多址接入源编码的方法。
