ABSTRACT

                             The mobile multimedia communication systems is rapid development the recent years. The main parameter is energy efficiency optimization and quality of service constraint for MIMO-OFDM communication. The various algorithm to be minimize the energy level for the transmitted signal. But it have some limitation. So we used proposed energy efficiency optimized power allocation (EEOPA).and to improve the energy efficiency for MIMO-OFDM mobile multimedia communication system. The EEOPA algorithm used to solve the problem of multi-channel optimize to multi target in single channel optimization. The method to calculate the channel characteristics using singular variable decomposition method (SVD).

                             An energy-efficiency model is first proposed for multiple input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) mobile multimedia communication systems with statistical QoS constraints. Employing the channel-matrix singular value decomposition (SVD) method, all sub channels are classified by their channel characteristics. Furthermore, the multichannel joint optimization problem in conventional MIMO-OFDM communication systems is transformed into a multi target single-channel optimization problem by grouping all sub channels. Therefore, a closed-form solution of the energy-optimization is derived for MIMO-OFDM mobile multimedia communication systems.
