—The purpose of this study is to propose a model that predicts the social and psychological factors that affect the individual's collaborative learning outcome in group projects. The model is established on the basis of two theories; the multilevel analysis and the cooperative game theory (CGT). In CGT, a group of players form a coalition and a set of(More)
In this paper, we compare the performance of two peak-to-average power ratio (PAPR) reduction schemes. Specifically, selected mapping (SLM) and partial transmit sequence (PTS) schemes are investigated. The analysis was performed for an OFDM system aligned with the IEEE 802.16e standard with 256 and 1024 subcarriers. The results indicate that SLM has(More)
This paper proposes a cooperative spectrum sensing scheme for cognitive radio networks using a polynomial classifier. The proposed scheme utilizes either coherent or cyclostationary features in the received signal at each node and the extracted features are used by a central node to make to a global decision about the availability of spectrum holes for use(More)
