Polar coded distribution matching

A fixed-length to fixed-length binary distribution matcher based on polar coding is presented that can generate an output sequence with a target probability distribution in a reversible way. An algorithm to obtain the required parameters and their proper approximations are provided. The method is fu...

Zusammenfassung:	A fixed-length to fixed-length binary distribution matcher based on polar coding is presented that can generate an output sequence with a target probability distribution in a reversible way. An algorithm to obtain the required parameters and their proper approximations are provided. The method is further extended to support arbitrary output lengths and transmission over noisy channels.
