A detailed study of the OFDM technique is developed in this paper, followed by a general overview of the systems used to implement it. To support these studies, several systems were simulated modeled under MATLAB. The systems produced are versatile and can be used to study the performance that resul...

OFDM is successfully used in many wireless digital communication system over multipath channels. One of the principal disadvantages of OFDM is the occurrence of high PAPR. OFDM signals are very sensitive to nonlinear effects due to the high PAPR, which leads to the power inefficiency in the RF secti...

Communication signals over power-line channels can be affected greatly by impulsive noise (IN). The effect of this noise is commonly reduced with the application of a nonlinear preprocessor at the receiver such as blanking or clipping that blanks and/or clips the received signal when it exceeds a ce...

Alamouti code is a simple space-time code that can be used for transmit diversity systems. This is a class of easily decoded space-time codes that achieve full diversity order in Rayleigh fading channels. Alamouti exist only for certain numbers of transmit antennas and do not provide array gain like...

Distribution networks are widest part of electrical grids. Due to low voltage and large expansion, the most of electric energy losses is related to these networks. Reconfiguration and capacitor placement are used in distribution networks, mainly to reduce power loss and improve voltage profile. In t...

The Antenna is a device which radiates or receives electromagnetic wave. The single input single output antenna has very low capacity and poor data rate which is overcome by Multiple input multiple output technology. The MIMO technology enables the higher data rate with great enhancement in capacity...
