Intelligent Sensors for Human Motion Analysis
The book, "Intelligent Sensors for Human Motion Analysis," contains 17 articles published in the Special Issue of the Sensors journal. These articles deal with many aspects related to the analysis of human movement. New techniques and methods for pose estimation, gait recognition, and fall detection have been proposed and verified. Some of them will trigger further research, and some may become the backbone of commercial systems
Holistic Biquadratic IIR Filter Design for Communication Systems Using Differential Evolution
Digital IIR filter implementations are important
building blocks of most communication systems. The chosen
number format (fixed-point, floating-point; precision) has a
major impact on achievable performance and implementation
cost. Typically, filter design for communication systems is based
on filter specifications in the frequency domain. We consider
IIR filter design as an integral part of communication system
optimisation with implicit filter specification in the time domain
(via symbol/bit error rate). We present a holistic design flow
with the system's bit error rate as the main objective. We
consider a discrete search space spanned by the quantised filter
coefficients. Differential Evolution is used for efficient sampling of
this huge finite design space. We present communication system
performance (based on bit-true simulations) and both measured
and estimated receiver IIR chip areas. The results show that very
small number formats are acceptable for complex filters and that
the choice between fixed-point and floating-point number formats
is nontrivial if precision is a free parameter
