Active Aperture Control and Sensor Modulation for Flexible Imaging
In the paper, we describe an optical system which is capable of providing external access to both the sensor and the lens aperture (i.e., projection center) of a conventional came...

A Supervised Learning Approach to Adaptation in Practical MIMO-OFDM Wireless Systems
—MIMO-OFDM wireless systems require adaptive modulation and coding based on channel state information (CSI) to maximize throughput in changing wireless channels. Traditional adap...

Analytical results about the robustness of FMT modulation with several prototype pulses in time-frequency selective fading chann
In this paper we study the performance of Filtered Multitone (FMT) modulation systems in time-frequency selective fading channels. FMT generalizes the OFDM scheme through the deplo...

On the Interaction Between Channel Coding and Hierarchical Modulation
1 Classical systems using hierarchical modulation (such as DVB-SH) involve a "high-priority" (HP) and a "lowpriority" (LP) bit stream that are separately and in...
