In this paper, we investigate the timing and carrier
frequency offset (CFO) synchronization problem in decode and
forward cooperative systems operating over frequency selective
channels. A training sequence which consists of one orthogonal
frequency-division multiplexing (OFDM) block having a tile
structure in the frequency domain is proposed to perform synchronization.
Timing offsets are estimated using correlation-type
algorithms. By inserting some null subcarriers in the proposed tile
structure, we propose a computationally efficient subspace decomposition-
based algorithm for CFO estimation. The issue of optimal
tile length is studied both theoretically and through simulations.
By judiciously designing the tile size of the pilot, the proposed
algorithms are shown to have better performance, in terms of
synchronization errors and bit error rate, than the time-division
multiplexing-based training method and the computationally demanding
space-alternating generalized expectation-maximization

DPFC
In this paper, we introduced a new series-shunt type FACTS controller called as distributed power flow controller to
improve and maintain the power quality of an electrical power system. This DPFC method is same as the UPFC used to
compensate the voltage sag and the current swell these are voltage based power quality problems. As compared to UPFC
the common dc link capacitor is removed and three individual single phase converters are used instead of a three phase
series converter. Series referral voltages, branch currents are used in this paper for designing control circuit. The evaluated
values are obtained by using MATLAB/SIMULINK.
