In recent years large scientific interest has been devoted to joint data decoding and parameter estimation techniques. In this paper, iterative turbo decoding joint to channel frequency and phase estimation is proposed. The phase and frequency estimator is embedded into the structure of the turbo decoder itself, taking into consideration both turbo interleaving and puncturing. Results show that the proposed technique outperforms conventional approaches both in terms of detection capabilities and implementation complexity.

With the increasing penetration of renewable energies as distributed generation (DG) in smart grid scheme, technical problems arise in both distribution and transmission system level. Undesirable voltage is the main problem for connection of DGs in distribution systems while excessive reactive power demand transmission system is the major concern for Transmission System Operators. The low power generation capacity of DER (Distributed Energy Resources) has motivated the need for integration of different types of DERs and loads in the form of micro-grid to enhance the power generation capacity, reliability and marketability of dispersed type of micro-sources [12, 13]. Current harmonics and Reactive power consumption are the two power quality issues that are addressed in this thesis
