Flooding-Assisted Informed Dynamic Scheduling for Rateless Codes

As part of the tradeoff between error performance, decoding complexity and the overhead of rate-less codes, the combination of Incremental Decoding (ID) and Informed Dynamic Scheduling (IDS), known as IDIDS (Incremental Decoding with Informed Dynamic Scheduling), is an attractive solution in Binary Symmetric Channels (BSC). However, applying IDIDS in the AWGN (Additive White Gaussian Noise) channel may cause a degradation in BER performance, since the incrementally received symbols from the AWGN channel may not be immediately utilized in the decoding process directed by IDS.
