A multiple-input multiple-output software defined radio (MIMO-SDR) platform was developed for implementation of MIMO transmission and propagation measurement systems. This platform consists of multiple functional boards for baseband (BB) digital signal processing and frequency conversion of 5 GHz-band radio frequency (RF) signals. The BB boards have capability of arbitrary system implementation...

Computed Tomography is a technique that can be performed using a set of X-ray images to re-create a three dimensional dataset which contains information about internal structure. Analysis of multilayered Printed Circuit Boards with their components using this technique allows for the non destructive evaluation of internal layers of failed boards. This report presents the results of computerised...

This paper describes the integration of printed circuit board design and fabrication into a computer architecture course. These printed circuit boards utilized 7400-series chips to realize an 8-bit ALU having the functions ADD, OR, ADD, SUB, and set-less-than. Students designed and laid out the boards using electronic tools. Their designs were sent out for fabrication and the resulting boards w...

We propose demonstrating an IEEE 802.11ah wireless local area network (WLAN) prototype that is configured as a self-contained machine-2-machine (M2M) wireless sensor system. Because the IEEE 802.11ah protocol standardization is under way, no commercial-off-the-shelf (COTS) IEEE 802.11ah Wi-Fi product is available yet. However, the proposed prototype has the potential to solve this issue and all...

As part of the development of a new international radio-telescope SKA (Square Kilometre Array), three phased-array prototypes with increasing complexity have been developed. The final SKA telescope will consist of more than one million receiving antenna elements and will operate in the frequency range of 200 to 2000 MHz. One of the challenges of the next generation radio telescopes for astronom...
