Adaptive Modulation for MIMO Systems with Channel Prediction Errors
The performance of multiple-input multiple-output (MIMO) systems using spatial multiplexing is analyzed under channel prediction errors. We derive exact closed-form expressions for...

Adaptive codebook for beamforming in limited feedback MIMO systems
—We propose a new scheme for limited feedback in MIMO systems. We consider transmit beamforming and receiver maximal ratio combining as a base for our work, and propose a novel b...

CMA and Soft Decision-Directed Scheme for Semi-Blind Beamforming of QAM Systems
— We propose a semi-blind adaptive beamforming approach for wireless systems that employ high-throughput quadrature amplitude modulation signalling schemes. A minimum number of t...
