Abstract
A method of transmitting information includes the steps of mapping an information word to first and second code words using first and second mapping functions, and transmitting the first and second code words. The information word is selected from a set of information words with each of the information words in the information word set having a first predetermined length, and the first code word is selected from a set of code words with each of the code words in the code word set having a second predetermined length greater than the first predetermined length. The second code word is selected from the code word set, and the first and second mapping functions are defined such that each of the information words of the information word set are mapped to two different code words of the code word set. Related systems and terminals are also discussed.
