Multicarrier spread spectrum: a coding perspective

The paper reveals the interrelation between multicarrier spread spectrum (MC-SS) transmission and multilevel coding (MLC). It is shown that MC-SS systems can be interpreted as a multilevel code with repetition codes in the levels. The paper is intended to provide new insights into both MC-SS systems and MLC. For both schemes, a lot of theory has been provided by numerous publications and particular parts of the existing theory for one scheme can be applied to the other.
