Capacity of CDMA system depends on an interference level in the system. There are therefore RRM (Radio Resources Management) functions, which are responsible for supplying optimum coverage, ensuring efficient use of physical resources and providing the maximum planned capacity. A call admission control algorithm based on load factor evaluation and a fuzzy(More)
The capacity of CDMA (Code Division Multiple Access) systems is interference limited. Therefore radio resources management (RRM) functions are used. They are responsible for supplying optimum coverage, ensuring efficient use of physical resources, and providing the maximum planned capacity. This paper deals with admission control techniques for UMTS(More)
ADS-B (Automatic Dependent Surveillance - Broadcast) is a key enabler for current and especially future ATM (Air Traffic Management) surveillance applications. The ADS-B communication link, 1090 MHz channel, suffers from congested environment, which may negatively impact the performance of corresponding surveillance applications. This paper presents several(More)
