The phase response of a recursive all-pass digital phase-equalizer is inherently non-linear with respect to its coefficients. In this paper, we first derive an approximate phase-error function whose numerator and denominator are approximated as linear functions of the phase-equalizer coefficients. Then, we propose a new design algorithm for fitting the phase response of an all-pass digital phase-equalizer...
The increasing demand for computing capability is driving the appearance of diverse parallel paradigms. Recently, MPI+OpenMP hybrid paradigm codes have been proved high performance efficiency in many applications and have been widely studied. But its relationship with MPI and OpenMP paradigm codes still need further study. In this paper, we focus on two aspects, the overhead and the number of processors...
In this paper, we propose a new technique called rotated-cone (Rcone) programming for designing all-pass (AP) phase-equalization circuit that is used in linearizing the nonlinear phase communication channels. Since AP digital circuit has unity-gain at all frequencies, we only need to consider the phase approximation for an given desired phase response. Basically, such a phase approximation problem...
This article analyzed the design elements during the process of project-oriented instructional design according to the characteristics of project-based teaching. And then, it proposed the scenario of project-oriented structured design based on the curriculum of webpage design.
