• ### Performance analysis of burst admission-control protocols

Publication Year: 1995, Page(s):7 - 14

| | PDF (556 KB)

The paper investigates the performance of two simple burst admission-control protocols for ATM networks. In the first approach, called tell-and-go', the source transmits its messages immediately in the form of bursts as soon as it receives the message from its application layer. In the second approach, called tell-and-wait', the source first reserves the bandwidth along the virtual circuit using... View full abstract»

• ### Multiple call hand-off problem with queued hand-offs and mixed platform types

Publication Year: 1995, Page(s):31 - 39
Cited by:  Papers (19)
| | PDF (608 KB)

Cellular communication systems that support a mixture of platform types and queuing of hand-off calls are considered. In pure loss systems, if there are no channels available at the target gateway, the hand-off attempt fails and the call is forced-to terminate. In delay systems however, hand-off calls can be held in queue while the supporting mobile is within a transition region where acceptable p... View full abstract»

• ### Optimal design of a finite-buffer polling network with mixed service discipline and general service order sequence

Publication Year: 1995, Page(s):1 - 6
| | PDF (348 KB)

Polling schemes have been widely used in LANs, MANs, and distributed systems. The authors design a polling network (system) in which each station is finite-buffered and is served according to a mixed service discipline and a general service order sequence. They first analyse the network by means of an imbedded Markov chain approach to obtain probability generating functions (PGFs) for the number o... View full abstract»

• ### Novel laser intersatellite communication system employing optically preamplified PPM receivers

Publication Year: 1995, Page(s):15 - 20

| | PDF (384 KB)

An original scheme for the utilisation of optically preamplified (EDFA) PPM receivers in intersatellite laser communications is presented. In order to facilitate high bit rate operation an analysis is presented for a PPM system employing threshold detection. When operating at the STM-1 bit rate of 155 Mbit/s and using conservative parameters the authors' model demonstrates a possible receiver sens... View full abstract»

• ### Pragmatic approach to soft-decision decoding of linear block codes

Publication Year: 1995, Page(s):40 - 47
Cited by:  Papers (2)  |  Patents (1)
| | PDF (620 KB)

The complexity of algorithms to perform soft-decision decoding on block codes has impeded their use in practical systems. The authors investigate correlation decoding along with hard-decision decoding. The proposed method uses a hard-decision decoder that decodes to a codeword. Although this codeword may be in error, it is usually close in Hamming distance to the transmitted codeword. Correlation ... View full abstract»

• ### Signal-to-interference calculations for modern TDMA cellular communication systems

Publication Year: 1995, Page(s):21 - 30
Cited by:  Papers (25)
| | PDF (644 KB)

Signal-to-interference ratios (SIRs) for time division multiple access (TDMA) systems using frequency hopping, power control, and discontinuous transmissions are calculated for tessellated hexagonal cellular clusters where the transmissions are subjected to an inverse fourth power path loss law and log-normal fading. Graphs of SIR against the number of cells per cluster for different voice activit... View full abstract»
