Real-time convex optimization in signal processing
Convex optimization signal processing coefficient of algorithm filtering array design
2015/8/7
Convex optimization has been used in signal processing for a long time, to choose coefficients for use in fast (linear) algorithms, such as in filter or array design; more recently, it has been used t...
We review some of the issues involved in using different plasmonic guided-wave structures for modulation, switching and filtering.
