Overseeing Warehouse Design Using MDA in Entire Lifecycle
Model Driven Architecture (MDA) is presented as an approach to system specification and interoperability, defined by the use of several formal models in order to describe the complete lifecycle of designing, deploying, integrating and managing applications. Beside, many conceptual methods have been exposed to solve different parts of a Data...

A Review: PAPR Reduction Techniques in MIMO OFDM System
Orthogonal Frequency Division Multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. It is one of the modulation techniques which are multi-carrier, gives a high spectral efficiency, immunity to the frequency selective fading channels, power efficiency and multipath delay spread tolerance. It is more advantageous over...
