The Equivalence of Semidefinite Relaxation MIMO Detectors for Higher-Order QAM
The Equivalence of Semidefinite Relaxation MIMO Detectors for Higher-Order QAM
In multi-input-multi-output (MIMO) detection, semidefinite relaxation (SDR) has been shown to be an efficient high-performance approach. Developed initially for BPSK and QPSK, SDR has been found to be capable of providing near-optimal performance (for those constellations). This has stimulated a number of recent research endeavors that aim to apply SDR …
