Abstract:
A method for data transmission to a receiving host, the transmitted data being coded for forward error correction, includes providing a pre-defined set Xk of symbols, having k symbols, at the transmitting host. An individual subset Xnh of the pre-defined set Xk, comprising nh symbols, is provided at each receiving host. An encoded symbol is calculated by the transmitting host based on a pre-defined rateless code. The calculated encoded symbol and the information with which symbols of set Xk is associated is transmitted to each of the receiving hosts. The encoded symbol is decoded by each receiving host using a decoding algorithm based on a pre-defined rateless code. Repeating the steps until each receiving host has retrieved from the received encoded symbols the respective difference set of symbols.
