This letter considers transmit precoding schemes based on the maximum signal-to-leakage-and-noise ratio (SLNR) in multiuser MIMO systems with single-antenna receivers. The closed-form solution of SLNR design is generally given in the form of the eigenvector associated to the maximum eigenvalue. In this letter, analytic expressions of SLNR-based solutions(More)
This paper proposes a linear transmit filter design to maximise Weighted Sum Capacity (WSC) in multiuser MultipleInput Multiple-Output (MU-MIMO) systems. The proposed scheme is based on a modified signal-to-leakage-plus-noise ratio (SLNR) criterion, which integrates receiver structures and power allocations into the precoder design and can efficiently(More)
This paper presents linear transceiver designs for MIMO interfering broadcast channels (MIMO IFBC). A new global objective, referred to as a Total Signal-to-Leakage-plus-Noise Ratio (TSLNR), is proposed and is solved based on alternating optimisation. The algorithm is also proven to converge. The proposed objective is further modified into an Individual(More)
In this letter, equivalent expressions of transmit precoding solutions based on the maximum signal-to-leakageplus-noise ratio (SLNR) are derived for multiuser MIMO systems with multi-antenna receivers. The performance of the SLNR precoding scheme is also analysed based on this equivalent form. Further, it is shown that the SLNR scheme can be viewed as a(More)
The exact and simple distributions of finite random matrix theory (FRMT) are critically important for cognitive radio networks (CRNs). In this paper, we unify some existing distributions of the FRMT with the proposed coefficient matrices (vectors) and represent the distributions with the coefficient-based formulations. A coefficient reuse mechanism is(More)
In our five-dimensional cosmological model, we investigate the role of a Lorentz violating vector “æther” field on the moduli stabilization mechanism. We consider the case of a space-like æther field on a compact circle with Maxwell-type kinetic term. The Casimir energy of certain combinations of massless and massive bulk fields generates a stabilizing(More)
