The voice Krlang capacity is analyzed ID a imiliiaotenna combined voice-data CDMA Reverse Link (RL). The influence of two different spatial combining techniques: Optimal Combining (OC) and Maximal Ratio Combining (MRO) on the voice Erlangs is evaluated when a single scheduled High Data Rate (HDR) data channel is shared by users desiring HDR services. The impact of randomly arriving data users o...

1 Introduction This Recommendation is the first in a series of three Recommendations that cover international telecommunications forecasting. In the operation and administration of the international telephone network, proper and successful development depends to a large degree upon estimates for the future. Accordingly, for the planning of equipment and circuit provision and of telephone plant ...

This paper studies the performance of radio assignment algorithms for portable access in cellular systems. Several channel access procedures are proposed and simulated using block oriented network simulator (BONeS) simulation of a model 36-port system. Simulation results exhibit that load-sharing system with LIBTA algorithm is better than directed retry system with the same algorithm by around ...

the probability of losing a customer in m/g/n/0 and gi/m/n/0 loss queuing systems withheterogeneous servers is minimized. the first system uses a queue discipline in which a customer who arriveswhen there are free servers chooses any one of them with equal probability, but is lost otherwise. providedthat the sum of the servers rates are fixed, loss probability in this system attains minimum val...

We consider a compound Poisson risk model where part of the premium is paid to the shareholders as dividends when the surplus exceeds a specified threshold level. In this model, we are interested in computing the moments of the total discounted dividends paid until ruin occurs. However, instead of employing the traditional argument which involves conditioning on the time and amount of the first...

In this paper, we analyze the performance of a signal-to-interference ratio (SIR)-based admission control strategy on the uplink in cellular code-division multiple-access (CDMA) systems with voice and data traffic. Most studies in the current literature to estimate CDMA system capacity with both voice and data traffic do not take into account admission control based on SIR constraints. Here, we...
