An MPSoC-Based QAM Modulation Architecture with Run-Time Load-Balancing

QAM is a widely used multilevel modulation technique, with a variety of applications in data radio communication systems. Most existing implementations of QAM-based systems use high levels of modulation in order to meet the high data rate constraints of emerging applications. This paper presents the architecture of a highly parallel QAM modulator, using MPSoC-based design flow and design methodology, which offers multirate modulation. The proposed MPSoC architecture is modular and provides dynamic reconfiguration of the QAM utilizing on-chip interconnection networks, offering high data rates (more than 1 Gbps), even at low modulation levels (16-QAM).
