ABSTRACT

Another advantage of the MC combined with an ISI channel is that it is possible to design channel independent MC such that the receiver is able to blindly identify the input signal. Such MC have been named polynomial ambiguity resistant MC (PARMC) and were studied in Chapters 8-10. We have shown that an MC to be a PARMC is necessary and sufficient for the blind identifiability. Surprisingly, we have shown that any block MC is not a PARMC. In other words, using a block MC at the transmitter, the receiver is not able to always recover an input signal, where the input signal constellation is not in the consideration. We have characterized PARMC in many cases and introduced an algebraic blind identification algorithm.
