Abstract
A transmitter is provided that shapes uniformly-distributed bits into a non-uniformly distributed bits according to a parity check matrix of a linear code such that a product of the parity check matrix and the non-uniformly distributed bits equals the uniformly-distributed bits. Similarly, receiver is provided that recovers the uniformly-distributed bits from the non-uniformly distributed bits through a multiplication of the non-uniformly-distributed bits with the parity check matrix.
