Adaptive Piecewise Linear Predistorters for Nonlinear Power Amplifiers With Memory
(Institute of Electrical and Electronics Engineers, 2012-07)
We propose novel direct and indirect learning predistorters (PDs) that employ a new baseband simplicial canonical piecewise linear (SCPWL) function. The performance of the proposed PDs is easily controlled by varying the ...
High-Order AFEM for the Laplace–Beltrami Operator: Convergence Rates
(Springer, 2016-12)
We present a new AFEM for the Laplace–Beltrami operator with arbitrary polynomial degree on parametric surfaces, which are globally W∞1 and piecewise in a suitable Besov class embedded in C1 , α with α∈ (0 , 1 ]. The idea ...
