ALACA: a platform for dynamic alarm collection and alert notification in network management systems
(John Wiley and Sons Ltd., 2017)Mobile network operators run Operations Support Systems that produce vast amounts of alarm events. These events can have different significance levels and domains and also can trigger other ones. Network operators face the ... -
Base station cooperation in orthogonal frequency division multiple access (OFDMA) systems
(2009)Achieving the targeted data rates for next generation wireless communication systems requires using frequency reuse ratio 1 in these systems, but this in turn results in significant intercell interference observed especially ... -
An FPGA implementation architecture for decoding of polar codes
(2011)Polar codes are a class of codes versatile enough to achieve the Shannon bound in a large array of source and channel coding problems. For that reason it is important to have efficient implementation architectures for polar ... -
Novel predistortion algorithm for OFDMA
(2009)The RF amplifier in a wireless communication system is usually non-linear in nature. If such an amplifier is used in OFDMA based systems, it will cause serious degradation. This degradation will be both in terms of the ... -
An optimal network dimensioning and initial energy assignment minimizing the monetary cost of a heterogeneous WSN
(2009)In this paper, a novel method is proposed to dimension a randomly deployed heterogeneous Wireless Sensor Network (WSN) of minimum monetary cost satisfying minimum coverage and minimum lifetime requirements. We consider ... -
A strong user authentication protocol for GSM
(2005)Traditionally, the authentication protocols for cellular phone networks have been designed for device authentication rather than user authentication, which brings certain limitations and restrictions on the functionality ...
