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.…
Precoding in Multiple-Antenna Broadcast Systems with a Probabilistic Viewpoint
Amin Mobasher, Amir K. Khandani
In this paper, we investigate the minimum average transmit energy that can be obtained in multiple antenna broadcast systems with channel inversion technique. The achievable gain c…
Fairness in Multiuser Systems with Polymatroid Capacity Region
Mohammad A. Maddah-Ali, Amin Mobasher, Amir Kayvan Khandani
For a wide class of multi-user systems, a subset of capacity region which includes the corner points and the sum-capacity facet has a special structure known as polymatroid. Multia…
LLL Reduction Achieves the Receive Diversity in MIMO Decoding
Mahmoud Taherzadeh, Amin Mobasher, Amir K. Khandani
Diversity order is an important measure for the performance of communication systems over MIMO fading channels. In this paper, we prove that in MIMO multiple access systems (or MIM…
Communication Over MIMO Broadcast Channels Using Lattice-Basis Reduction
Mahmoud Taherzadeh, Amin Mobasher, Amir K. Khandani
A simple scheme for communication over MIMO broadcast channels is introduced which adopts the lattice reduction technique to improve the naive channel inversion method. Lattice bas…
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…
