Design of optimal hybrid form FIR filter
This paper examines the problem of designing the optimal hybrid form FIR filter subjected to a minimum cycletime constraint. We formulate the problem as one of determining the optimal partitioning of the hybrid form FIR filter into subsections. Each subsection can be optimized independently using other methods. We then show how the problem can be solved efficiently using a dynamic programming a...
متن کاملA descent method for explicit computations on curves
It is shown that the knowledge of a surjective morphism $Xto Y$ of complex curves can be effectively used to make explicit calculations. The method is demonstrated by the calculation of $j(ntau)$ (for some small $n$) in terms of $j(tau)$ for the elliptic curve with period lattice $(1,tau)$, the period matrix for the Jacobian of a family of genus-$2$ curves complementing the classi...
متن کاملA hybrid steepest descent method for constrained convex optimization
This paper describes a hybrid steepest descent method to decrease over time any given convex cost function while keeping the optimization variables into any given convex set. The method takes advantage of properties of hybrid systems to avoid the computation of projections or of a dual optimum. The convergence to a global optimum is analyzed using Lyapunov stability arguments. A discretized imp...
متن کاملA hybrid descent method for the two-edge disjoint survivable network design problem with relays
In this paper, we study the network design problem with relays considering network survivability. This problem arises in telecommunications and logistic systems. The design problem involves selecting two edge-disjoint paths between source and destination node pairs and determining the location of the relays in the network to minimize the network cost. A constraint is imposed on the distance tha...
متن کاملDesign of multiplierless prototype filter for two-channel filter bank using hybrid method in FCSD space
In this work, a hybrid method-based design of multiplierless two-channel filter bank has been proposed with a given stopband attenuation (As) and roll-off factor. Windowing method has been used for efficient design of a prototype filter with novelty of exploiting quantised coefficients in canonical sign digit (CSD) and factorised canonical sign digit (FCSD) space by merging the concept of parti...
