A model is derived for the distribution of burst errors that impulse noise causes with ADSL. This model is used to analyze the performance of the codes in the presence of impulse noise. The bit error rate with crosstalk or Gaussian noise is also determined and results are compared to those for uncoded transmission. It is found that the compact disc codes are very effective for ADSL.<<ETX>>","PeriodicalId":343080,"journal":{"name":"IEEE Global Telecommunications Conference GLOBECOM '91: Countdown to the New Millennium.

An analysis is made of the delay-throughput performance of this network for uniform traffic patterns. Results show that in geographically distributed applications the maximum achievable throughput (normalized to the transmission rate) is typically between 0.4 and 0.5 per channel. For example, the maximum achievable throughput is between 400 and 500 Gb/s for a 1000-channel system with a 1-Gb/s transmission rate. In a centralized switch, the (normalized) maximum achievable throughput can approach 0.8 per channel. These values are higher than previously published optical systems.<<ETX>>","PeriodicalId":343080,"journal":{"name":"IEEE Global Telecommunications Conference GLOBECOM '91: Countdown to the New Millennium.

An optimal and a heuristic algorithm have been designed and tested. The results show that the heuristic algorithm can find multicast routes that are close to optimal within a response time that is significantly lower than that of the optimal algorithm. Further analysis of the experimental data suggests a hybrid implementation in which the optimal and heuristic algorithms are run in parallel with a set time limit. The algorithms and the discussion provided also apply to other networks, including wide-area communication networks, with a two-hop structure.<<ETX>>","PeriodicalId":343080,"journal":{"name":"IEEE Global Telecommunications Conference GLOBECOM '91: Countdown to the New Millennium.

Their finite state sequential machine is defined and the achievable rate region is discussed. For the code construction aspect, two general rules are proposed as follows: (1) Always leave suitable redundancy when using the output word which is false in decreasing the running digital sum (RDS) in the absolute value. (2) If state splitting is inevitable, then first try to split the states with small n-l (where n and l are the accumulated RDS and encoding delay, respectively) and with large delay l. By using these rules, several DC-free (d,k) codes are constructed. It is shown that, by following the general rules, the trial work can be substantially reduced.<<ETX>>","PeriodicalId":343080,"journal":{"name":"IEEE Global Telecommunications Conference GLOBECOM '91: Countdown to the New Millennium.

The probability of internal blocking is reduced significantly when two or more parallel channels interconnect stages of crossbars. Using small buffers (about 20 packets) at the outputs of the networks a throughput exceeding 90% can be achieved by using 3 channels per port. With further increase in the number of channels and buffer size the throughput approaches 100%. These networks can be used in telecommunication switching employing asynchronous transfer mode and in multiprocessor systems.<<ETX>>","PeriodicalId":343080,"journal":{"name":"IEEE Global Telecommunications Conference GLOBECOM '91: Countdown to the New Millennium.
