Partial erasure channels have recently been introduced to model erasure events in applications such as flash memories. In these channels, some information may remain after an erasure event. After reviewing these channels, we present results in two directions. First, we show how multilevel coding and multistage decoding may be applied on different partial erasure channels and classify cases when the subchannels are simple erasure channels. Second, we consider Luby Transform (LT) codes over partial erasure channels. We present a modified decoding process for these codes and compare their efficiency with standard LT codes on the q-ary erasure channel.
