Using Open-Ended Design Projects In An Open Lab To Teach Lifelong Learning Skills In An Ic Design Course, David Parent

The ABET criterion, recognition for and the ability to engage in life-long learning, is one of the most important, given that we as engineering educators can not teach every concept that students will encounter over the span of a 20-40 year career as an engineer. We believe that one method to teach and verify this critical skill in the area of Integrated Circuit (IC) design, is to have the students learn IC CAD tools by following well crafted tutorials and then complete open-ended IC design projects in an open lab. The project is supposed to be a full custom design …

A non-data aided carrier recovery technique using digital modulation format identification called multi-mode PLL (Phase Locked Loop) is proposed. This technique can be interpreted as a modulation identification method that is robust against static phase and frequency offsets. The performance of the proposed technique is studied and the analytical expressions are derived for the probability of lock detection, acquisition time over AWGN channel in the cases of M-PSK and M-QAM modulations with respect to frequency offset and signal-to-noise ratio.

In this talk, the unique characteristics of ultra wideband (UWB) communications systems are introduced. Receiver design considerations are presented. Focus is on the relation between the symbol duration and the delay spread of the channel. This determines whether the receiver should use a Rake receiver (Spread-spectrum system) or an equalizer (multiple carrier or OFDM system).
