Abstract
Multilevel coded I-Q modulation (I-Q MCM) is proposed in this paper. By utilizing the orthogonal character of QAM modulation, the in-phase and quadrature components of the signal can be encoded and decoded independently in I-Q MCM, which can greatly decrease the decoding complexity and time delay. Through simulation, we can also see this I-Q MCM doesn´t give rise to any performance loss compared with traditional MCM scheme.
