Abstract: Integrated Services Digital Broadcasting for Terrestrial (ISDB-T) One-Seg is a Japanese standard for digital television specifically for mobile reception. It uses Orthogonal Frequency Division Multiplexing (OFDM) that provides robustness against multipath fading. A novel approach called Compressed Sensing (CS) has been implemented for estimating the Channel State Information (CSI). The CS improves the spectral efficiency by estimating the CSI with less measurement. However CS requires high computational cost that makes the method difficult for actual implementation. This paper proposes a new approach for channel estimation using reduced size sparse measurement matrix combined with Modified Orthogonal Matching Pursuit (MOMP) algorithm. The simulation shows that the proposed method provides less execution time for CSI calculation.

Abstract: Business process modeling has become an ever more popular and essential part of today’s organizations. The business process can be visually represented, depicting the activities, and independencies while at the same time highlighting any inefficiencies and potential areas for improvement. The important of embedding good business process modeling techniques into an organization cannot be underestimated. This paper introduces the audience to business process modeling, its benefits, and guidelines for introducing it into an organization and the key concepts and elements that underpin good business process modeling.
