The Capacity of MIMO Channels with Per-Antenna Power Constraint
We establish the optimal input signaling and the capacity of MIMO channels under per-antenna power constraint. While admitting a linear eigenbeam structure, the optimal input is no longer diagonalizable by the channel right singular vectors as with sum power constraint. We formulate the capacity optimization as an SDP problem and solve in closed-form the optimal input covariance as a function o...
متن کاملPower Allocation for Precoding in Large-Scale MU-MIMO Systems with Per-Antenna Constraint
Large-scale MIMO systems have been considered as one of the possible candidates for the next-generation wireless communication technique, due to their potential to provide significant higher throughput than conventional wireless systems. For such systems, Zero-Forcing (ZF) and Conjugate Beamforming (CB) precoding have been considered as two possible practical spatial multiplexing techniques, an...

متن کاملOptimal Energy Beamforming under Per-Antenna Power Constraint
Energy beamforming (EB) is a key technique to significantly enhance the efficiency of wireless power transfer (WPT). In this paper, we study optimal EB under per-antenna power constraint (PAC) which is more practical than conventional sum-power constraint (SPC) at multi antenna energy transmitter (ET). We consider a broadcast network, where one multi antenna ET with PAC, transfers wireless ener...
متن کاملFixed Point Iteration Method
We discuss the problem of finding approximate solutions of the equation 0 ) ( x f (1) In some cases it is possible to find the exact roots of the equation (1) for example when ) (x f is a quadratic on cubic polynomial otherwise, in general, is interested in finding approximate solutions using some numerical methods. Here, we will discuss a method called fixed point iteration method and a part...
