State of the art baseband DSP platforms for Software Defined Radio: A survey
Software Defined Radio (SDR) is an innovative approach which is becoming a more and more promising technology for future mobile handsets. Several proposals in the field of embedded systems have been introduced by different ...
Embedded Multi-Core Systems Dedicated to Dynamic Dataflow Programs
Multimedia applications and embedded platforms are both becoming very complex in order to improve user experience. Thus, multimedia developers need high-level methods to automate time-consuming and error-prone tasks. Dynamic ...
A Fast Unambiguous Acquisition Algorithm for BOC-Modulated Signals
This paper proposes a fast unambiguous acquisition technique for BOC-modulated signals. We remove the ambiguities (side-peaks) of the BOC autocorrelation function, exploiting a reduced-complexity (real and symmetric) filter ...
Noncontact Respiration Monitoring during Sleep with Microwave Doppler Radar
This paper demonstrates the measurement of respiration waveform during sleep with a noncontact radar sensor. Instead of measuring only the respiration rate, the methods that allow monitoring the absolute respiration ...
Numerical Analysis of the Power Balance of an Electrical Machine with Rotor Eccentricity
The power balance in the numerical simulation of a cage induction machine with eccentric rotor has been studied. The asymmetrical air gap flux density distribution caused by the non-uniform air gap due to eccentricity ...
Effectiveness modelling of digital contact-tracing solutions for tackling the COVID-19 pandemic
Since the beginning of the coronavirus (COVID-19) global pandemic, digital contact-tracing applications have been at the centre of attention as a digital tool enabling citizens to keep their social distancing, which appears ...
Capacitive Measurement of Facial Activity Intensity
The measurement of the intensity of facial muscle activity can be used in several applications such as human–computer interaction and behavioural science. A new method for the intensity measurement is presented. It is based ...
Performance evaluation of time-multiplexed and data-dependent superimposed training based transmission with practical power amplifier model
The increase in the peak-to-average power ratio (PAPR) is a well known but not sufficiently addressed problem with data-dependent superimposed training (DDST) based approaches for channel estimation and synchronization in ...
