Approximate SER for M-PSK using MRC and STTD Techniques over Fading Channels

Author 1: Mahmoud A. Khodeir Author 2: Muteeah A. Jawarneh

In this study, approximate symbol error rate (SER) expressions for M-ary phase shift keying (M-PSK) modulation scheme over independent and identically distributed (i.i.d) slow-flat Rician and Rayleigh fading channels are derived. Simulation results show the superior impact of using the maximum ratio combining (MRC) space diversity technique on the overall… Read full abstract & cite →

Sociomaterial analysis of Music Notation Lessons: Virtual work and digital materialities

Author 1: Demosthenes Akoumianakis

The present research rests and elaborates on sociomaterial aspects of virtual practices, as manifested through distributed and collaborative work. This is approached through an interpretive case study of music notation lessons (MNLs) using the DIAMOUSES system. Our empirical data suggest that sociomateriality shifts the focus of designing interactive technologies from… Read full abstract & cite →
