Capacity Analysis of MIMO OFDM System using Water filling Algorithm
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 8
Abstract
In present correspondence we develop a proposed water filling algorithm for MIMO fading channel (Rayleigh Fading channel). Orthogonal Frequency Division Multiplexing (OFDM) become the chosen modulation technique for wireless communication. Multiple access points or small base stations send independent coded information to multiple mobile terminals through orthogonal Code division multiplexing channels. MIMO is a promising high data rate interface technology. It is well known the capacity of MIMO can be significantly enhanced by employing a proper power budget allocation in wireless cellular network .The singular value decomposition and water filling algorithm have been employed to measure the performance of MIMO OFDM integrated system. When Nt transmit and Nr represented antennas are employed, outage capacity is increased. In MIMO OFDM we transmit different stream of data through different antennas. We show that as we increase the power budget in the water filling algorithm the mean capacity of the system increased .The proposed work investigated with Mat lab.
