Abstract: Systems and methods of reducing transmission time are described. Uniform-sized original packets are generated from a data frame having a payload with an identifier and data. The packets include the identifier, total block number, block index that specifies an order of the packet, and the data. The packets are encoded to form redundant packets with the identifier, block number, block index and redundant data. The available block index for the original and redundant packets are different. The packets are transmitted by individual modems over different channels at transmission rates that are each configured to minimize free space in an input buffer of the modem and are dependent on feedback from the receiver. The feedback indicates a difference between the transmission rate and a reception rate. The encoding rate is dependent on the original packets over the original and redundant packets or a maximum transmission rate over the remaining transmission rates.
