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...

The hardware used to implement the digital techniques discussed previously is the main focus of this chapter. We will first discuss digital signal processors (DSPs) and the functions they must perform. Next, two commercially available DSPs are described. Current high-performance VLSI architectures for signal processing are introduced including parallel processing, bit-serial processing, systoli...

This paper describes a coherent optical receiver, ELO. 1 ELO where drifts of the carrier phase and state of polarization are L E (2) estimated with digital signal processing. The complex amplitude LO,y 2 J jLO of the signal is entirely restored with such receiver. where ELO is the constant amplitude of LO. The 90' optical hybrids in Fig.1 generate electric fields E1. .8 at double balanced
