Vertical tracks on the sidewall of a silicon die using 3D holographic photolithography (2011)
Journal Article
Toriz-Garcia, J., Williams, G., McWilliam, R., Seed, N., Purvis, A., Soulard, F., …Ivey, P. (2011). Vertical tracks on the sidewall of a silicon die using 3D holographic photolithography. Journal of Micromechanics and Microengineering, 21(8), Article 085034. https://doi.org/10.1088/0960-1317/21/8/085034

We describe the patterning of multiple 10 µm wide conductive tracks down the vertical sidewall of a 500 µm thick silicon die. A novel photolithographic technique is used, which utilizes a computer-generated hologram mask in conjunction with a diffrac...

Three-dimensional holographic lithography by an iterative algorithm (2011)
Journal Article
Cowling, J., Williams, G., Purvis, A., McWilliam, R., Toriz-Garcia, J., Seed, N., …Ivey, P. (2011). Three-dimensional holographic lithography by an iterative algorithm. Optics Letters, 36(13), 2495-2497. https://doi.org/10.1364/ol.36.002495

We have applied an iterative algorithm for hologram design with multiple output image planes arranged in close proximity to create continuous patterns within an imaging volume. These holograms have been designed for photolithography on three-dimensio... Read More about Three-dimensional holographic lithography by an iterative algorithm.

A Singular-Value-Based Adaptive Modulation and Cooperation Scheme for Virtual-MIMO Systems (2011)
Journal Article
Jiang, J., Thompson, J. S., & Sun, H. (2011). A Singular-Value-Based Adaptive Modulation and Cooperation Scheme for Virtual-MIMO Systems. IEEE Transactions on Vehicular Technology, 60(6), 2495-2504. https://doi.org/10.1109/tvt.2011.2155686

This paper presents a practical virtual multiple-input-multiple-output (MIMO) system that implements bit-interleaved coded modulation (BICM) and compress-and-forward (CF) cooperation. A minimum mean square error (MMSE) receiver is considered since it... Read More about A Singular-Value-Based Adaptive Modulation and Cooperation Scheme for Virtual-MIMO Systems.

Spectrum Occupancy Statistics and Time Series Models for Cognitive Radio (2011)
Journal Article
Wang, Z., & Salous, S. (2011). Spectrum Occupancy Statistics and Time Series Models for Cognitive Radio. Journal of Signal Processing Systems, 62(2), 145-155. https://doi.org/10.1007/s11265-009-0352-5

While dedicated spectrum occupancy monitoring provides vital information for frequency planning and management, it usually cannot tell the common properties in spectrum occupancy. As a complement, the models approach can be used to describe and compa... Read More about Spectrum Occupancy Statistics and Time Series Models for Cognitive Radio.
