MULTI-LEVEL ENCODER AND DECODER WITH SHAPING AND METHODS FOR MULTI-LEVEL ENCODING AND DECODING WITH SHAPING

摘要

An encoder is proposed for encoding a message into channel input symbols. The encoder is configured to divide the message for obtaining message parts, encode the message parts into encoded parts such that at least one encoded part has a non-uniform distribution, map the encoded parts into the channel input symbols. A channel input symbol is based on a plurality of encoded parts.
