New Results on Selection Diversity over Fading Channels
… bit error rate performance of five different selection diversity combining schemes over slow, frequency non-selective Rayleigh, Nakagami-m and Ricean fading channels. Aside from the classical selection diversity, generalized selection combining and the "maximum output" selection methods, two …

Analysis of a Two-Branch Maximal Ratio and Selection Diversity System with Unequal Branch Powers and Correlated Inputs for a Rayleigh Fading Channel
… an analytical framework for analyzing two-branch diversity systems for a Rayleigh fading channel. In many cases the fading received at both branches (i.e. a two-antenna element system) is correlated because of the proximity of the antenna elements to each other. It is also not uncommon for a …

Phase-locked loop, delay-locked loop, and linear decorrelating detector for asynchronous multirate DS-CDMA system
… scheme. Therefore, we propose Hybrid Selection Diversity/ Maximal Ratio Combining (Hybrid SD/MRC) one-shot window linear decorrelating detector (LDD) for asynchronous DS-CDMA systems. The selection diversity scheme at the input of the Hybrid SD/MRC LDD is based on choosing the branch …

Optimum combining of handset diversity antennas
… was analyzed for single antenna performance, selection diversity combining, maximum ratio combining, and optimum combining.

Simulation and Mathematical Tools for Performance Analysis of Low-Complexity Receivers
… and terrestrial repeater signals using a selection diversity (single antenna) receiver has also been performed. The thesis also develops a general mathematical framework for studying the efficacy of a sub-optimal generalized selection combining (GSC) diversity receiver over generalized …

Ultra-Wideband for Communications: Spatial Characteristics and Interference Suppression
… UWB signals and NBI by implementing a simple selection diversity scheme. It is shown that this simple scheme can provide strong benefits in performance.

Social Change through Community Innovation: Feminist and Participatory Design Approaches to Organizing Inclusive, Equitable, and Joyful Hackathons
… of hackathons, including poor problem-selection, diversity and inclusion issues around who participates, the exploitation of unpaid labor, their limited impact, and the dangers of positing purely technological solutions to sociotechnical issues. At the same time, hackathons have …

Sexual selection and biological diversification: Patterns and processes
… The results presented here suggest that sexual selection is an important force in evolution. In Chapters I and II, I investigate the relationship between male courtship displays and speciation. Chapter I utilizes the multiple sister-taxa comparison method to test the hypothesis that sexual …
