A new algorithm for power allocation in MIMO-OFDM systems with a beam-forming scheme

Along with the growing increase of the demand for establishing a safe and fast connection between different users, for the purpose of transferring large audio-visual data using a wireless technology, a great number of studies have been carried out on the Multiple-Input Multiple-Output Orthogonal Frequency-Division Multiplexing Systems. In the algorithm presented in this article, first a simple, but efficient, model for multiple-input multiple-output orthogonal frequency-division multiplexing systems is offered. Besides, where the Channel state matrix in the Transmitter is known to us, we have tried to find a desirable capacity for such a system, putting the discussions of the information theory into practice as well as applying the method of singular value decomposition in channel matrixes. The simulation results prove such a claim.
