VLSI Design of Large-Scale Soft-Output MIMO Detection Using Conjugate Gradients
(2015)2015 IEEE International Symposium on Circuits and Systems (ISCAS)We propose an FPGA design for soft-output data detection in orthogonal frequency-division multiplexing (OFDM)-based large-scale (multi-user) MIMO systems. To reduce the high computational complexity of data detection, our design uses a modified version of the conjugate gradient least square (CGLS) algorithm. In contrast to existing linear detection algorithms for massive MIMO systems, our method avoids two of the most complex tasks, namely ...Conference Paper -
CS-MUVI: Video compressive sensing for spatial-multiplexing cameras
(2012)2012 IEEE International Conference on Computational Photography (ICCP)Compressive sensing (CS)-based spatial-multiplexing cameras (SMCs) sample a scene through a series of coded projections using a spatial light modulator and a few optical sensor elements. SMC architectures are particularly useful when imaging at wavelengths for which full-frame sensors are too cumbersome or expensive. While existing recovery algorithms for SMCs perform well for static images, they typically fail for time-varying scenes ...Conference Paper -

High performance mid- and far-infrared quantum cascade lasers
(2004)2004 IEEE LEOS Annual Meeting Conference Proceedings (LEOS 2004)Low threshold and highly tunable mid-infrared lasers are demonstrated based on a bound to continuum active region. Tunable emission over more than 150 cm/sup -1/ have been achieved. Terahertz quantum cascade lasers based on a bound to continuum active regions combined with an optical phonon extraction. Operation up to 117 K is demonstrated.Conference Paper -
