In this paper we provide an adaptive modulation approach that uses adaptive pilot symbols which both pilot spacing and power allocation on pilot symbols are optimized in single in...
— In this paper, we consider single user throughput optimization problem for continuous flat fading channels of multiple-input multiple-output (MIMO) system. It is known that ch...
Abstract-- Two-tier networks, comprising a conventional cellular network overlaid with shorter range hotspots (e.g. femtocells, distributed antennas, or wired relays), offer an eco...
— Consider the problem of resource allocation on the downlink of a cellular OFDMA system. A fairness constraint is defined by a minimum data rate, a maximum bit-error rate and a...
Abstract— We consider both the single-user and the multiuser power allocation problems in MIMO systems, where the receiver side has the perfect channel state information (CSI), a...
