Quadrature rules with quasi-degree of exactness

open access: yes
Many quadrature rules are designed to be exact for easily integrable functions similar to the integrand. The Gauss formula with $n$ nodes is exact on the space of all polynomials of degree $\le 2n-1$ and it represents a unique optimal interpolatory ...

On the Performance of Band-Limited Asynchronous DS-CDMA over Nakagami-m Channels

open access: yes, 2006
In this paper we investigated the BER performance of DS-CDMA using various chip-waveforms, which include three time-limited chip-waveforms and two band-limited chipwaveforms.
