Fast Fourier Transform (FFT) processors employed with pipeline architecture consist of series of Processing Elements (PE) or Butterfly Units (BU). BU or PE of FFT performs multiplication and addition on complex numbers. This paper proposes a single BU to compute radix-2, 8 point FFT in the time domain as well as frequency domain by replacing a series of PEs. This BU comprises of fused floating ...

| We present a new low-complexity bit-parallel canonical basis multiplier for the eld GF2 m generated by a n all-one-polynomial. The proposed canon-ical basis multiplier requires m 2 , 1 XOR gates and m 2 AND gates. We also extend this canonical basis multiplier to obtain a new bit-parallel normal basis multiplier.

Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing technology is an advanced transmission technique for wireless communication systems. In this paper, the 64 point pipeline FFT/IFFT processor is introduced for efficient implementation of OFDM architecture. The IFFT processor is used to modulate the subcarrier in transmitter section and FFT processor demodulate the subcarr...

We introduce an entropy-like proximal algorithm for the problem of minimizing a closed proper convex function subject to symmetric cone constraints. The algorithm is based on a distance-like function that is an extension of the Kullback-Leiber relative entropy to the setting of symmetric cones. Like the proximal algorithms for convex programming with nonnegative orthant cone constraints, we sho...

This paper proposes two improved modular multiplication algorithms based on Barrett and Montgomery modular reduction. The algorithms are simple and especially suitable for hardware implementations. Four large sets of moduli for which the proposed methods apply are given and analyzed from a security point of view. By considering state of art the attacks on public-key cryptosystems, we prove that...

82 www.ijeas.org  Abstract—This paper presents a hybrid differential evolution with multiplier updating (HDE-MU) to solve the complex combined heat and power economic dispatch (CHPED) problems. Transmission losses and valve-point effects of conventional thermal generators are taken into account. The hybrid differential evolution (HDE) has the ability to efficiently search and actively explore ...

We investigate the possibility of solving mathematical programs with complemen-tarity constraints (MPCCs) using classical algorithms and procedures from nonlinear programming. Although MPCCs do not satisfy a constraint qualiication, we establish suucient conditions for their Lagrange multiplier set to be nonempty in two diierent formulations. MPCCs that have nonempty Lagrange multiplier sets an...

We introduce a spectrum for arbitrary varieties. This generalizes the definition by Steenbrink for hypersurfaces. In the isolated complete intersection singularity case, it coincides with the one given by Ebeling and Steenbrink except for the coefficients of integral exponents. We show a relation to the graded pieces of the multiplier ideals by using a relation to the filtration V of Kashiwara ...
