ITERATIVE WATER FILLING ALGORITHM BASED CHANNEL CAPACITY ESTIMATION FOR MIMO-OFDM

摘要

The capacity and coverage of Multiple input multiple output orthogonal frequency division multiplexing systems can be enhanced by employing a proper radio resource allocation to assign the available resources in an economic way for multiuser environment. For efficient allocation of the power to the MIMO channels to enhance the capacity of the MIMO network should be used of water filling algorithm. The performance of MIMO-OFDM has been evaluated using singular value decomposition and water filling system. The capacity and SNR performance for SISO and MIMO system without and with water filling algorithm has also been demonstrated here for the comparative analysis. Different modulation schemes are implemented in this work forthe verification of performance of proposed scheme.
