Abstract :
Fountain codes, as a kind of rateless codes, can be used to transmit information over any unstable channels. In wireless communications, the channels may suffer from different kinds of fading, which results in unpredictable performance in some scenarios. In this paper, we start to investigate the performance of fountain codes over wireless channels by taking its encoding mechanism into account. Here three different random encoding generators are considered. Some simulation results indicated that the selection of random encoding generators has a certain impact on the performance of LT codes for different signal-to-noise ratio over AWGN channels.
