Joint Power Loading of Data and Pilots in OFDM Using Imperfect Channel State Information at the Transmitter
— The search for optimality in the design of channel precoders and training symbols in block processing communication systems is one of paramount importance. Finding the best tra...

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...

A MIMO channel perturbation analysis for robust bit loading
In narrowband multiple-input multiple-output (MIMO) communication systems, when the channel state information (CSI) is known perfectly at the transmitter and the receiver, techniq...

Multiuser MIMO Downlink Transmission Over Time-Varying Channels
—— The performance of multiuser MIMO downlink systems with block diagonalization (BD) relies on the channel state information (CSI) at the transmitter to a great extent. For ti...

Joint turbo channel estimation and data recovery in fast fading mobile coded OFDM
Orthogonal frequency division multiplexing (OFDM) system suffers extra performance degradation in fast fading channel due to intercarrier interference (ICI). Combing frequency dom...
