Generic iterative search-centre-shifting K-best sphere detection for rank-deficient SDM-OFDM systems
Motivation: The sphere detector (SD) constitutes a computationally efficient solution to the maximum likelihood (ML) detection problem in uncoded multiple-input, multiple-output (MIMO) systems [1, 2]. However, when employed in an iterative detection aided channel coded system, the SD has to generate soft information for every transmitted bit, which requires the observation of a high number of h...
متن کاملThe exquisite corpse: a shifting view of the shifting balance.
In 1925, a game called ‘exquisite corpse’ was invented by a group of surrealists to harness the random power of imagination through collaboration. Working either with words or drawings, an exquisite corpse was begun by one member of the group, who then folded the paper so that his or her contribution was obscured and then passed it to the next member. The game (named after one of their first re...
متن کاملShifting Sugars and Shifting Paradigms
No organism lives in a constant environment. Based on classical studies in molecular biology, many have viewed microbes as following strict rules for shifting their metabolic activities when prevailing conditions change. For example, students learn that the bacterium Escherichia coli makes proteins for digesting lactose only when lactose is available and glucose, a better sugar, is not. However...
متن کاملAchievements of the Cochrane Iran Associate Centre: Lessons Learned
Healthcare decision-making is a process that mainly depends on evidence and involves increasing numbers of stakeholders, including the consumers. Cochrane evidence responds to this challenge by identifying, appraising, integrating and synthesizing high-quality evidence. Recently, a collaborative effort has been initiated in Iran with Cochrane to establish a representati...
متن کاملThe Silently Shifting Semicolon
Memory consistency models for modern concurrent languages have largely been designed from a system-centric point of view that protects, at all costs, optimizations that were originally designed for sequential programs. The result is a situation that, when viewed from a programmer’s standpoint, borders on absurd. We illustrate this unfortunate situation with a brief fable and then examine the op...
