Systems and methods of synchronizing a fountain code transmitting end and receiving end. In one embodiment, the fountain code transmitting end includes a first pseudorandom number generator, a second pseudorandom number generator, and a first transceiver. The method includes generating, at the first pseudorandom number generator, a first random number based on a seed. The method further includes generating, at the second pseudorandom number generator, a first plurality of unique random numbers based on the first random number. The method also includes selecting, at the fountain code transmitting end, a first subset of data blocks of a plurality of data blocks based on the first plurality of unique random numbers. The method further includes generating, at the fountain code transmitting end, a first communication block based on the first subset of data blocks. The method also includes transmitting, via the first transceiver, the first communication block and the seed.
