Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. An apparatus, comprising:
a buffer operable to receive first bits at a first rate and output k second bits at a second rate different than the first rate; and
a distribution matching (DM) encoder operable receive the k second bits at the second rate, such that, based on the k second bits, the DM encoder outputs n symbols, the n symbols being indicative of a transmission probability distribution, whereby first modulation symbols are transmitted more frequently than second modulation symbols, k being a first integer and n being a second integer,
wherein the buffer is a first buffer, the first bits and second bits are included in an input data stream, the apparatus including a second buffer operable to store third bits of the input data stream, the third bits being sign bits associated with the transmission probability distribution.
