coherent detection method using dsp for demodulation of signal and subsequent equalization of propagation impairments
FREE-DOWNLOAD MG Taylor – Photonics Technology Letters, research, 2004 – Abstract—A new approach to coherent detection is demon- strated which achieves the same high sensitivity as homodyne detection but without the need to phase lock the local oscillator laser. In addition, 1470 ps/nm of chromatic dispersion is compen- sated with zero net
digital power factor correction (PFC) control strategy optimized for dsp
FREE-DOWNLOADW Zhang, G Feng, YF Liu… – Power Electronics, research … Abstract—A predictive algorithm for digital control power factor correction (PFC) is presented in this paper. Based on this algorithm, all of the duty cycles required to achieve unity power factor in one half line period are calculated in advance by digital signal processors (dsps). […]
mixed analog digital multirate signal processing
FREE-DOWNLOAD SK Mitra… ABSTRACT To achieve higher levels of integration there has been a growing interest in recent years in designing systems containing both analog and digital functions on a single integrated circuit. In most cases, these are inherently multirate systems because of the different
