Adaptive PSAM in SIMO systems with imperfect CSI in Rayleigh fading channels
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...

Throughput Optimization for Continuous Flat Fading MIMO Channels with Estimation Error
— 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...

Resource allocation in OFDMA downlink with reduced feedback overhead
— 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...

Optimum Power Allocation for Single-User MIMO and Multi-User MIMO-MAC with Partial CSI
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...
