Wireless mobile communication have grown dramatically in last decades. Due to increased usage of wireless mobile networks and communications in our everyday life, the society has become extremely exposed to cyber security attacks and threats in this environment. In order to provide a basis for further in detail discussion on attacks and security mechanisms in this challenging environment, this paper...
Sophisticated voice source estimation techniques, such as closed-phase pitch synchronous inverse filtering method, relay on accurate estimates of glottal closure instants (GCIs). In this paper, a group delay approach to GCI estimation is presented. Specifically, the average group delay and the energy weighted group delay measures are discussed in detail. We propose an improvement to the implementation...
This paper proposes a novel Finite Impulse Response adaptive filter. The proposed algorithm is named Intelligent Bee Colony (IBC) algorithm. It takes some features from the Artificial Bee Colony algorithm and combines them with the elements from the classical gradient-based adaptive filter theory to produce an adaptive filter that is characterized by a very fast convergence rate. IBC algorithm is...
