The availability of fast and cost effective digital processing technology makes digital pre-distortion attractive for power amplifier linearization since it promises high power efficiency and flexibility. Digital pre-distortion task can be divided into three sub tasks: modeling of the power amplifier (PA), adaptive identification of the model parameters, and development of the pre-distorter. Th...

Fuzzy Hermite interpolation of 5th degree generalizes Lagrange interpolation by fitting a polynomial to a function f that not only interpolates f at each knot but also interpolates two number of consecutive Generalized Hukuhara derivatives of f at each knot. The provided solution for the 5th degree fuzzy Hermite interpolation problem in this paper is based on cardinal basis functions linear com...

The problem of verifying multi-threaded execution against the memory consistency model of a processor is known to be an NP hard problem. However polynomial time algorithms exist that detect almost all failures in such execution. These are often used in practice for microprocessor verification. We present a low complexity and fully parallelized algorithm to check program execution against the pr...

A Memory Cross Volterra model for Doherty power amplifiers (PA) with delay mismatch is presented in this letter. During the design process of amplifier, gain, efficiency and operation bandwidth are mostly considered. Delay difficult to avoid kind dual-path circuit, which reduces modeling performance traditional behavioral models. The proposed Model (MCVM) derived from combination three memory p...
