Performance Analysis and Design of Non-orthogonal Multiple Access for Wireless Communications (1910.00946v1)

Abstract: In this thesis, we study performance analysis and resource allocation designs for non-orthogonal multiple access (NOMA) in wireless communication systems. In contrast to conventional orthogonal multiple access (OMA) schemes, NOMA allows multiple users to share the same degree of freedom via superposition coding and the successive interference cancelation (SIC) decoding. Inspired by the solid foundations from the information theory perspective, NOMA has rekindled the interests of researchers as a benefit of the recent advancement in signal processing and silicon technologies. However, comprehensive performance analysis on NOMA and practical resource allocation designs to exploit potential gains of NOMA in terms of spectral and energy efficiency have not been fully studied and investigated in the literature. This thesis attempts to address these problems by providing a unified performance analysis and a systematic resource allocation design for NOMA in wireless communication systems.
