Orthogonal Frequency Division Multiplexing (OFDM) is a well known technique for the broadband wireless communication system. However, a main problem in OFDM is its vulnerability to frequency offset errors due to which the orthogonality is destroyed that result in Inter carrier Interference (ICI). ICI causes power leakage among subcarriers thus degrading the system performance. This paper studie...

In order to facilitate interoperability in a network composed of next generation lambda-switch-capable equipment, this document defines a standard lambda label format that is compliant with the Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplexing (CWDM) grids defined by the International Telecommunication Union Telecommunication Standardization Sector. The l...

Integer division has been known since 1986 [4, 13, 12] to be in slightly non-uniform TC, i.e., computable by polynomial-size, constant depth threshold circuits. This has been perhaps the outstanding natural problem known to be in a standard circuit complexity class, but not known to be in its uniform version. We show that indeed division is in uniform TC. A key step of our proof is the discover...

This paper examines the implementation of Finite Field arithmetic, i.e. multiplication, division, and exponentiation, for any standard basis GF(2m) with m≤8 on a DSP datapath. We introduce an opportunity to exploit cells and the interconnection structure of a typical binary multiplier unit for the Finite Field operations by adding just a small overhead of logic. We develop division and exponent...

In this paper we seek to account for scalar implicatures and Horn’s division of pragmatic labor in game-theoretical terms by making use mainly of refinements of the standard solution concept of signaling games. Scalar implicatures are accounted for in terms of Farrell’s (1993) notion of a ‘Neologism-Proof’ equilibrium together with Grice’s maxim of Quality. Horn’s division of pragmatic labor is...

One of the main characteristics of object-oriented database management systems is the explicit representation of relationships between objects. A simple example for a query addressing these relationships arises, if we assume the object types Company , and Division with the relationship has division from Company to Division. In this case a query might ask for the companies which have a division ...
