Abstract This study investigates the relationship between board gender diversity and sustainability performance using a sample of 205 Nordic‐listed firms across countries Denmark, Finland, Norway, Sweden over period 2002–2020. Drawing on social role theory upper echelons theory, our results show positive significant association performance. Furthermore, extends finding indicating that “critical...

In this paper the influence of the channel estimation error on the performance of the closed loop Tx diversity algorithms for WCDMA is studied for high number of Tx antennas. The analysed algorithms are recently proposed generalised closed loop Tx diversity, allantenna Tx diversity and one-antenna selection Tx diversity. It was shown that generalised closed loop Tx diversity algorithm is more r...

Diversity schemes that exploit wireless channel variations in time, frequency, and space are an essential component for combating multipath fading in modern wireless communications systems. To evaluate performance and thereby design reliable and resource-efficient systems, designers require analytical tools that capture the salient, if not precise, characteristics of the fading channel model an...

Blog distillation (blog feed retrieval) is a task in blog retrieval where the goal is to rank blogs according to their recurrent relevance to a query topic. One of the main properties of blog feed retrieval is that the unit of retrieval is a collection of documents as opposed to a single document as in other IR tasks. This collection retrieval nature of blog distillation introduces new challeng...

In this paper, we extend ultra-wideband (UWB) single input single output (SISO) systems with a hybrid pulse amplitude and position modulation (PAPM) to single input multiple output (SIMO) systems using receive antenna diversity. The performance of a rake receive diversity combining scheme for UWB SIMO systems with a PAPM is examined in a log-normal multipath fading channel and also compared wit...

In this paper, blind adaptive multiuser detection (MUD) technique is developed for uplink transmission in multiuser space diversity DS-CDMA system to overcome multipath fading effect and multiple access interference. The system consists of a space diversity, a precombining blind adaptive detector (PBAD), and a weight adaptation technique based on the minimization of the mean output energy (MOE)...
