Method and apparatus for encoding and decoding information signals

摘要

A method and apparatus for coding and decoding information are disclosed. The method is for encoding a message that includes a first set of binary digits. Each binary digit has a first value ("0") or a second value ("1"). The method includes receiving a first set of binary digits, generating a second set of binary digits in response to the first set of binary digits (Y), and selecting the values of binary digits in the second set such that the number of binary digits having the first binary value in the second set is higher than the number of binary digits having the first binary value in the first set.
