A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

ABSTRACT
Over the last few years the interest in distributed generation and island operation of small production units has increased. Many of the existing such units are hydro power stations with induction generators. These are not initially constructed for island operation, but with some extra equipment this kind of operation is feasible. In this paper the behavior of two parallel-operated induction generators driven by hydro turbines are studied during load steps. The influence of a STATCOM based voltage regul ....etc

Hi,
you need to specify the parameters required for your circuit. I suggest that you search the net for the circuits. But your textbook is the best. Take any book on Linear Integrated Circuits from the library(for example Linear integrated circuits by roy choudhury). The theory is simple and you can easily design a voltage to frequency converter yourself. ....etc

Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc

Detecting Power Grid Synchronization Failure

Tarun Agarwal
Synchronization means the minimization of difference in voltage, frequency and phase angle between the corresponding phases of the generator output and grid supply. An alternating current generator must be synchronized with the grid prior to connection. It can t deliver the power unless it is running at same frequency as the network. Synchronization must occur before connecting the generator to a grid. Synchronization can be achieved manually or automatically. The purpose of synchr ....etc
