WIPL-D (WIre PLate Dielectric) has become an increasingly popular Method of Moments (MoM) code used in computational electromagnetics (CEM) modeling. WIPL-D was chosen for parallelization under the Common High Performance Computing Software Support Initiative (CHSSI) program of the High Performance Computing Modernization Office (HPCMO). Hence, the new code(More)
—A new technique of arbitrary waveform direct digital frequency synthesis (DDFS) is introduced. In this method, one period of the desired periodic waveform is divided into sections, and each section is approximated by a series of Chebyshev polyno-mials up to degree. By expanding the resultant Chebyshev poly-nomials, a power series of degree is produced. The(More)
Reservations based admission control, using Multi-protocol Label Switching (MPLS) is the leading method being considered by traditional carriers for maintaining Quality of Service (QoS) when deploying Voice over Internet Protocol (VoIP). In this research we explore an alternative to reservations based admission control called Delay Based Congestion(More)
An automatic feedback control system that maintains an average bit error rate (BER) on decoded code words is proposed for log-likelihood ratio (LLR)error correction code (ECC) decoders. The input to the controller is the LLR output of the decoder, while the controller output is the decoder iteration parameter. The loop error signal is constructed by(More)
