Recent improvements in the speed and complexity of commercially available digital signal processing (DSP) devices have allowed digital techniques to be extended to a number of new areas. Now many applications in RF and communications are within the bandwidth capability of current generation DSP systems. This paper demonstrates a system developed recently for such applications. It uses standard ...

PSpice for Digital Signal Processing is the last in a series of five books using Cadence Orcad PSpice version 10.5 and introduces a very novel approach to learning digital signal processing (DSP). DSP is traditionally taught using Matlab/Simulink software but has some inherent weaknesses for students particularly at the introductory level. The ‘plug in variables and play’ nature of these softwa...

This thesis introduces a novel approach to programmable and low power platform design for audio signal processing, in particular hearing aids. The proposed programmable platform is a heterogeneous multi-processor architecture consisting of small and simple instruction set processors called mini-cores as well as standard DSP/CPU-cores that communicate using message passing. The work has been bas...

Meeting the needs of people with severe to profound hearing loss places enormous demands on a hearing instrument system. It has to make the most of narrowed residual dynamic range and the hearing instrument needs to accommodate marked individual differences in the optimal amplification strategy for compensating for severe to profound hearing loss. There also must be flexibly adjustable protecti...

In our work we have developed a new methodology for the design of nonlinear dynamical systems and signal processing algorithms In this paper, we discuss the basic concept of this approach, as well as some variations of the applied modeL We show the results of application of this approach in Signal estimation. We also compare the obtained results with that of Kalman filtering. The results indica...
