Talk Abstract:
It is well known and fundamental that the matched filter is the optimal detector for a signal immersed in additive white Gaussian noise. The matched filter is a continuous-time structure and always performs better than digital matched filters, which are optimal structures for detecting signals in additive white Gaussian noise based on a number of independent samples of the signal-plus-noise. In the case of non-Gaussian noise, only one other optimal detection structure is known, and that is the optimal (continuous-time) detector for signals immersed in Laplace noise. Meanwhile, the fundamental Gaussian distribution is a special case of the more flexible and descriptive generalized Gaussian distribution (GGD). In this talk, we derive the optimal detector for a signal immersed in additive GGD noise, which we dub the generalized matched filter. This detection scheme finds the absolute value of the difference between a replica of the transmitted signal and the received signal-plus noise, raises this absolute error to the βth power, and then integrates the resulting signal. This detection structure can, therefore, also be referred to as the absolute error power detector. We show that the matched filter is a special case of the absolute error power detector for GGD parameter β = 2, the Gaussian noise case, and that the optimal detector for Laplace noise is also a special case when β = 1. The optimal probability of error for binary signaling in additive white generalized Gaussian noise is assessed. The fundamental structure is also optimal for higher-level modulations after straightforward extensions.

How to Write an IEEE Style Paper and Get it Published?

Time & Date: 11am-12pm, Monday June 5, 2017

Talk Abstract:

Institute of Electrical and Electronics Engineers (IEEE) is world’s largest professional association which is best known, among other engineering disciplines, for its high quality flagship journal and conference publications. For electrical engineering graduate students and researchers, it is increasingly important to publish their research findings in core IEEE journals and conferences. However, most top IEEE journals and conferences typically have acceptance rate at 35% or much less, and it is also rare that a manuscript receives an outright acceptance. In this talk, I will introduce basic elements of an IEEE style paper, and offer some personal tips and strategies on how to improve the odds of acceptance. The goal of this presentation is to provide the proper guidance to the beginning graduate students so that, with some practice, they can write an IEEE style paper with high confidence. These graduate students can then focus more on the technical contributions of their work.
