Cutoff rate for fixed-composition coding over energy constrained AWGN channels
Oğuz, Nihat Cem (Bilkent University, 1990)Shannon showed that, under an energy constraint, the ensemble of shell constrained codes optimizes the cutoff rate for AVVGN channels. Unfortunately, this ensemble is not very practical since its input alphabet is the ... -
Performance analysis of two-level forward error correction for lostcell recovery in ATM networks
Oğuz, Nihat Cem; Ayanoğlu, E. (IEEE, 1995-04)The major source of errors in B-ISDN/ATM systems is expected to be buffer overflow during congested conditions, resulting in ATM cell losses which degrade the quality of service. It has been shown by many authors that the ... -
Performance of two-level forward error correction for lost cell recovery in ATM networks
Oğuz, Nihat Cem (Bilkent University, 1995)The major source of errors in Asynchronous Transfer Mode (ATM.) networks is expected to be buffer overflow during congestion, resulting in cell losses. The large ratio of the end-to-end propagation time for a typical ... -
Simulation study of forward error correction for lost packet recovery in B-ISDN/ATM
Oğuz, Nihat Cem; Ayanoğlu, E. (IEEE, 1993-05)We present the results of a simulation study for a virtual circuit connection over an ATM network where forward error correction is performed at both the ATM cell level and the packet data unit (PDU) level. A main conclusion ... -
A simulation study of two-level forward error correction for lost packet recovery in B-ISDN/ATM
Oğuz, Nihat Cem; Ayanoğlu, E. (IEEE, 1993)The major source of errors in B-ISDN/ATM systems is expected to be buffer overflow during congested conditions, resulting in lost packets. A single lost or errored ATM cell will cause retransmission of the entire packet ...
