From the communication channel and implementation aspects of communications, the transmission environement may be sufficiently degraded, e.g. a multipath fading channel, that acquiring and tracking a coherent demodulation reference signal is practically difficult. Coherent receivers require exact knowledge of the channel phase for optimum performance. Due to the difficult task of estimation cha...

This talk describes the reasons why η and η decays are an interesting topic of study for both theory and experiment. The main part discusses the results of the recent calculation of η → 3π at two-loop order in ChPT. Some puzzling aspects of the results compared to earlier dispersive calculations are highlighted. I also like to remind the reader of the use of η and η decays for studying the anom...

In order to shorten 3dB performance gap between the conventional differential detection and correlation detection in network coding, we consider multiple-symbol differential detection (MSDD) for two-way relay channel (TWRC) model. MSDD, which makes use of continuously N symbols to jointly detect N-1 symbols. However, the complexity of the maximum likelihood differential detection increases expo...

This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...
