Abstract

The MIMO technology utilizes different antennas at each terminal of a wireless link and greatly improves the link reliability and spectral efficiency of future wireless communication systems. This technology integrated with Orthogonal Frequency Division Multiplexing (OFDM), which is particularly proving a propitious entrant for upcoming next generation wireless systems including both mobile and fixed systems. Itprovides an attractive air-interface solution for next-generation wireless/cellular systems. In this paper Waterfilling algorithm has been used to optimize transmit power for maximizing the capacity. The Waterfilling algorithm successfully solved the problem of power allocation for MIMO-OFDM wireless network and adaptively allocate power to minimize BER performance and increasing the capacity in order to maintain the QoS requirements for a network. The proposed work is investigated by using Matlab tool.
