Matrix-Lifting Semi-Definite Programming for Decoding in Multiple Antenna Systems
Amin Mobasher, Amir K. Khandani
This paper presents a computationally efficient decoder for multiple antenna systems. The proposed algorithm can be used for any constellation (QAM or PSK) and any labeling method.…

A Near Maximum Likelihood Decoding Algorithm for MIMO Systems Based on Semi-Definite Programming
Amin Mobasher, Mahmoud Taherzadeh, Renata Sotirov +1
In Multi-Input Multi-Output (MIMO) systems, Maximum-Likelihood (ML) decoding is equivalent to finding the closest lattice point in an N-dimensional complex space. In general, this…
