In this paper, a set of 11 embedded machine control system patterns are presented. These patterns were identified during architectural assessments carried out at several sites of Finnish machine industry. The pattern set is categorized according to three major characteristics of such software: distribution, real-time, and fault tolerance. The pattern set(More)
Orthogonal Frequency-Division Multiplexing (OFDM) has become the preferred modulation scheme for both broadband and high bitrate digital wireless protocols because of its spectral efficiency and robustness against mul-tipath interference. Although the components and overall structure of different OFDM protocols are functionally similar, the characteristics(More)
