摘要：
We study coding schemes for the q-ary symmetric channel with moderate alphabet sizes q that are much smaller than the q = 2(256) considered as "entry level" in some recently proposed packet-based schemes. First, we show theoretical optimality of a simple layered scheme, then we propose a practical coding scheme based on a simple modification of standard binary LDPC decoding.
